Yet, modern machine learning pipelines offer a\r\npromising solution—provided their predictions yield correct conclusions. We\r\nfocus on Prediction-Powered Causal Inferences (PPCI), i.e., estimating the\r\ntreatment effect in an unlabeled target experiment, relying on training data with\r\nthe same outcome annotated but potentially different treatment or effect modifiers.\r\nWe first show that conditional calibration guarantees valid PPCI at population\r\nlevel. Then, we introduce a sufficient representation constraint transferring validity\r\nacross experiments, which we propose to enforce in practice in Deconfounded\r\nEmpirical Risk Minimization, our new model-agnostic training objective. We\r\nvalidate our method on synthetic and real-world scientific data, solving impossible\r\nproblem instances for Empirical Risk Minimization even with standard invariance\r\nconstraints. In particular, for the first time, we achieve valid causal inference\r\non a scientific experiment with complex recording and no human annotations,\r\nfine-tuning a foundational model on our similar annotated experiment." acknowledgement: "We thank the Causal Learning and Artificial Intelligence group at ISTA for the continuous feedback\r\non the project and valuable discussions.

The oscillations are current-voltage dual to those ordinarily observed in single junctions. The current-voltage dual circuit quantitatively accounts for temporal dynamics of the array, including the dependence on biasing conditions. Injection locking of the oscillations results in well-developed current plateaux. A thermal model explains the self-consistent reduction of the superconducting gap due to overheating of the array in the high-current state. Our work suggests that overheating determines the switching from the high-current state to the low-current state. acknowledged_ssus: - _id: M-Shop - _id: NanoFab acknowledgement: We gratefully acknowledge support from the Miba Machine Shop and the Nanofabrictation Facility at IST Austria.

Mapping neurons and resolving their individual synaptic connections can be achieved by volumetric imaging at nanoscale resolution1,2 with dense cellular labelling. Light microscopy is uniquely positioned to visualize specific molecules, but dense, synapse-level circuit reconstruction by light microscopy has been out of reach, owing to limitations in resolution, contrast and volumetric imaging capability. Here we describe light-microscopy-based connectomics (LICONN). We integrated specifically engineered hydrogel embedding and expansion with comprehensive deep-learning-based segmentation and analysis of connectivity, thereby directly incorporating molecular information into synapse-level reconstructions of brain tissue. LICONN will allow synapse-level phenotyping of brain tissue in biological experiments in a readily adoptable manner. acknowledged_ssus: - _id: Bio - _id: LifeSc - _id: ScienComp - _id: PreCl - _id: M-Shop - _id: E-Lib acknowledgement: 'We thank S.

Chapter 3 and 4 review the statistics of records, their connection to models of innovation and an application to the cultural evolution of sports.\r\n\tIn chapter 1 we present a modelling study from 2021 on the evolution of SARS-CoV-2. At that time the vaccine-resistant Omicron variant had not yet evolved. In our model we consider a population that is becoming vaccinated over time, while a pathogen is spreading in the population and eventually becoming resistant to the vaccine. We explore effective pharmaceutical and non-pharmaceutical interventions to prevent the emergence of vaccine resistance. \r\n\tIn chapter 2 we model a particular set of complex vaccination strategies, mosaic and pyramid vaccination, where an immunologically diverse portfolio of vaccines is considered. We find that a bet-hatching strategy, in which vaccine types are distributed in the population, is effective at hindering the evolution of vaccine resistance if mutation rates are high. \r\n\tIn chapter 3 we switch gears and present a review on the statistics of records. We highlight similarities and analogies to other models in the fields of statistical physics, evolution and innovation. This offers interesting complimentary perspectives on well-known models. \r\n\tIn chapter 4 we apply models of record statistics and innovation to study cultural evolution in sport. We propose a model of sport evolution that combines deterministic improvements in performance and stochastic bursts of improvements due to innovation.

Such deformations\r\neither preserve the intrinsic material geometry (e.g., folding paper) or modify it through\r\nlocalized contraction. Once transformed, the 3D shape can be further controlled to achieve a\r\ntarget functionality. A key challenge is to take the material specifications and the actuation\r\nprocess as input to automatically design the target 3D shape and its functionality. This thesis\r\npresents two novel computational pipelines for the design and control of shape-morphing\r\nstructures used to create functional prototypes.\r\nThe first pipeline borrows from the art of origami to fold paper into intricate shapes and\r\napplies this principle to make 3D lighting displays. We introduce, PCBend a computational\r\ndesign approach that covers a surface with individually addressable RGB LEDs, effectively\r\nforming a low-resolution surface by folding rigid printed circuit boards (PCBs). We optimize\r\ncut patterns on PCBs to act as hinges and co-design LED placement, circuit routing, and\r\nfabrication constraints to produce PCB blueprints. The PCBs are fabricated using automated\r\nstandard manufacturing services with LEDs embedded on them. Finally, the fabricated PCBs\r\nare cut along the contour and folded onto a 3D-printed support. The 3D lighting display is\r\nthen controlled to display complex surface light patterns.\r\nCreating 3D shapes through folding is only possible if their planar configuration, called ”unfolding” exists without any distortion or overlap. Existing methods often permit distortion\r\nor require multiple patches, which are unsuitable for fabrication pipelines that rely on folding\r\nnon-stretchable materials. We reinforce such fabrication pipelines by providing a geometric\r\nrelaxation to the problem, where the input shape is modified to admit overlap-free unfolding.\r\nThe second fabrication pipeline extends shape morphing to soft robotics by emulating nature’s\r\nblueprint of distributed actuation. Inspired by vertebrates, we build musculoskeletal robots\r\nusing modular active actuators, employing Liquid Crystal Elastomers (LCEs) as shrinkable\r\nartificial muscles integrated with 3D-printed bones. The chemical composition of LCEs is\r\naltered to enable untethered actuation through infrared radiation, allowing active control of\r\nindividual muscles and their corresponding bones. The combined motion of individual bones\r\ndefines the robot’s overall shape and functionality. Our proposed system significantly expands\r\nboth the design and control spaces of soft robots, which we harness using our computational\r\ndesign tools. We build several physical robots that exhibit complex shape morphing and varied\r\nterrain navigation, showcasing the versatility of our pipeline.\r\nThis thesis explores applications ranging from intricate light patterns displayed on 3D shapes\r\nformed by folding rigid PCBs to untethered robots that use contractile muscles to exhibit\r\nshape morphing and locomotion. Through these examples, the thesis highlights how computational design and distributed actuation, integrated with novel materials, can transform\r\npassive structures into functional prototypes." acknowledgement: "Financial support was provided by the European Research Council (ERC) under grant agreement No 715767 - MATERIALIZABLE: Intelligent fabrication-oriented Computational Design\r\nand Modeling that I gratefully acknowledge.\r\n" alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Manas full_name: Bhargava, Manas id: FF8FA64C-AA6A-11E9-99AD-50D4E5697425 last_name: Bhargava orcid: 0009-0007-6138-6890 citation: ama: 'Bhargava M.

For example, tiny perturbations, often imperceptible to\r\nthe human eye, can completely change the predictions of image classifiers. Despite a decade\r\nof research, the field has made limited progress in developing image classifiers that are both\r\naccurate and robust. This thesis aims to address this gap.\r\nAs our first contribution, we aim to simplify the process of training certifiably robust image\r\nclassifiers. We do this by designing a convolutional layer that does not require executing an\r\niterative procedure in every forward pass, but relies on an explicit bound instead. We also\r\npropose a loss function that allows optimizing for a particular margin more precisely.\r\nNext, we provide an overview and comparison of various methods that create robust image\r\nclassifiers by constraining the Lipschitz constant. This is important since generally longer\r\ntraining times and more parameters improve the performance of robust classifiers, making it\r\nchallenging to determine the most practical and effective methods from existing literature.\r\nIn 1-Lipschitz classification, the performance of current methods is still much worse than what\r\nwe expect on the simple tasks we consider. Therefore, we next investigate potential causes of\r\nthis shortcoming. We first consider the role of the activation function. We prove a theoretical\r\nshortcoming of the commonly used activation function, and provide an alternative without it.\r\nHowever this theoretical improvement does barely translate to the empirical performance of\r\nrobust classifiers, suggesting a different bottleneck.\r\nTherefore, in the final chapter, we study how the performance depends on the amount of\r\ntraining data. We prove that in the worst case, we might require far more data to train a\r\nrobust classifier compared to a normal one. We furthermore find that the amount of training\r\ndata is a key determinant of the performance current methods achieve on popular datasets.\r\nAdditionally, we show that linear subspaces exist with tiny data variance, and yet we can\r\nstill train very accurate classifiers after projecting into those subspaces. This shows that on\r\nthe datasets considered, enforcing robustness in classification makes the task strictly more\r\nchallenging.\r\n\r\n" alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Bernd full_name: Prach, Bernd id: 2D561D42-C427-11E9-89B4-9C1AE6697425 last_name: Prach citation: ama: Prach B.

While each of these projects tackles a topic in a different area of research, they all share a common thread in the type of topological structure they handle - a partition of space into volumes separated by interfaces that meet in non-manifold junctions.\r\n\r\nIn Chapter 2, we study clusters of soap bubbles from a simulation perspective. In particular, we develop a surface-only algorithm that couples large scale motion and shape deformation of soap bubble clusters with the small scale evolution of the thin film's thickness, which is responsible for visual phenomena like surface vortices, Newton's interference patterns, capillary waves, and deformation-dependent rupturing of films in a foam. We model film thickness as a reduced degree of freedom in the Navier-Stokes equations and from them derive three sets of equations governing normal and tangential motion of the soap film surface, as well as the evolution of the thin film thickness. We discretize these equations on a non-manifold triangle mesh, extending and adapting operators to handle complex topology. We also present an incompressible fluid solver for 2.5D films and an advection algorithm for convecting fields across non-manifold surface junctions. Our simulations enhance bubble solvers with additional effects caused by convection, rippling, draining, and evaporation of the thin film.\r\n\r\nIn Chapter 3, we introduce a multi-material non-manifold mesh-based surface tracking algorithm that converts mesh defects, such as overlaps, self-intersections, and inversions into topological changes. Our algorithm generalizes prior work on manifold surface tracking with topological changes: it preserves surface features like mesh-based methods, and it robustly handles topological changes like level set methods. Our method also offers improved efficiency and robustness over the state of the art. We demonstrate the effectiveness of the approach on a range of examples, including complex soap film simulations, such as those presented in Chapter 2, but with an order of magnitude more interacting bubbles than what we could achieve before, and Boolean unions of non-manifold meshes consisting of millions of triangles.\r\n\r\nLastly, in Chapter 4, we utilize developments in the theory of random geometric complexes facilitated by observations from Discrete Morse theory. We survey the methods and results obtained with this new approach, and discuss some of its shortcomings. We use simulations to illustrate the results and to form conjectures, getting numerical estimates for combinatorial, topological, and geometric properties of weighted and unweighted Delaunay mosaics, their dual Voronoi tessellations, and the Alpha and Wrap complexes contained in the mosaics." acknowledged_ssus: - _id: ScienComp acknowledgement: The project in Chapter 2 has received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme under grant agreement No. 638176.

This thesis explores geometric structures and dynamics on this space, with emphasis on their implications for physics, particularly hydrodynamics.\r\n\r\nOur investigation ranges from theoretical studies of infinite-dimensional symplectic and prequantum geometry to numerical computation of the time evolution of shapes. The thesis presents four main contributions.\r\n\r\nIn the first part, we introduce implicit representations of codimension-2 shapes using a class of complex-valued functions, and prove that the space of these implicit representations forms a prequantum bundle over the codimension-2 shape space. This reveals a new geometric interpretation of the canonical symplectic structure on the codimension-2 shape space.\r\n\r\nIn the second part, we use implicit representations to develop a simulation method for the dynamics of space curves. To handle chaotic systems such as vortex filaments in hydrodynamics, we exploit the infinite degrees of freedom, hidden in both the configuration and dynamics of implicit representations.\r\n\r\nIn the third part, we introduce new symplectic structures on the space of space curves, which generalize the only previously known symplectic structure on this space, allowing for new Hamiltonian dynamics of space curves.\r\n\r\nIn the fourth part, we apply a symplectic viewpoint to a differential geometric problem with practical applications.

In this article, we study how the main solution concepts, the discounted and undiscounted values, vary when these parameters are perturbed. We focus on the marginal values, introduced by Mills in 1956 in the context of matrix games—that is, the directional derivatives of the value along any fixed perturbation. We provide a formula for the marginal values of a discounted stochastic game. Further, under mild assumptions on the perturbation, we provide a formula for their limit as the discount rate vanishes and for the marginal values of an undiscounted stochastic game. We also show, via an example, that the two latter differ in general. acknowledgement: This work was supported by Fondation CFM pour la Recherche; the European Research Council [Grant ERC-CoG-863818 (ForM-SMArt)]; and Agence Nationale de la Recherche [Grant ANR-21-CE40-0020]. article_processing_charge: No article_type: original author: - first_name: Luc full_name: Attia, Luc last_name: Attia - first_name: Miquel full_name: Oliu-Barton, Miquel last_name: Oliu-Barton - first_name: Raimundo J full_name: Saona Urmeneta, Raimundo J id: BD1DF4C4-D767-11E9-B658-BC13E6697425 last_name: Saona Urmeneta orcid: 0000-0001-5103-038X citation: ama: Attia L, Oliu-Barton M, Saona Urmeneta RJ.

Mathematically, they represent a fundamental class of transformations and symmetries. Unlike spatial displacements, rotational transformations in three-dimensional space are non-commutative: the result of applying a sequence of rotations depends on the order of these operations. This feature makes the emergent physics that involves rotations rather intricate, but instrumental for studies of highly-interconnected many-body systems. In the presence of an environment, rotational properties of an object change, due to the interaction with particles of the environment. Owing to the complexity of this interaction, it can be engineered to exhibit certain properties of interest.

For example, while a boolean property may specify whether a server eventually grants every request it receives, a quantitative one may map each server execution to its average response time. This quantitative view is relatively well-studied in the context of static verification. However, although such properties often appear in practice as performance or robustness measures in a dynamic verification context, a general theoretical framework for their analysis and classification from a monitoring perspective is still missing.\r\n\r\nIn this thesis, we aim to develop such a framework that takes resource-precision tradeoffs of monitors as a central consideration. We present the first theory of monitorability for quantitative properties where monitors can be naturally approximate and compared regarding their precision and resource use. In particular, we show that additional monitor resources such as registers or states lead to strictly better approximations for some properties. To enable such analyses in a machine-model independent way, we describe an abstract notion of monitors that can be instantiated with concrete models of monitors. Within this framework, we study how abstract monitors behave and identify classes of properties amenable to approximate monitoring with resource-precision considerations. We then extend the boolean safety-liveness dichotomy and safety-progress hierarchy to the quantitative setting with a monitoring perspective. In particular, we prove that every property is the pointwise minimum of a safety property and a liveness property, and properties that are both safe and co-safe can be approximately monitored arbitrarily precisely using only finitely many states. We also study the classes of quantitative properties definable by finite-state quantitative automata and provide algorithms for deciding their safety or liveness as well as their safety-liveness decompositions. Finally, we present the first general-purpose tool for automating the analysis, verification, and monitoring of quantitative automata.\r\n\r\n\r\n" acknowledgement: "This work was supported in part by the Austrian Science Fund (FWF)\r\nunder grant Z211-N23 (Wittgenstein Award) and the ERC-2020-AdG 101020093.\r\n" alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Naci E full_name: Sarac, Naci E id: 8C6B42F8-C8E6-11E9-A03A-F2DCE5697425 last_name: Sarac citation: ama: Sarac NE.

The computational complexity of 0-Ext[μ] has been recently established by Karzanov and by Hirai: if metric μ is {\\em orientable modular} then 0-Ext[μ] can be solved in polynomial time, otherwise 0-Ext[μ] is NP-hard. To prove the tractability part, Hirai developed a theory of discrete convex functions on orientable modular graphs generalizing several known classes of functions in discrete convex analysis, such as L♮-convex functions. We consider a more general version of the problem in which unary functions fi(xi) can additionally have terms of the form cuv;iμ(xi,{u,v}) for {u,v}∈F, where set F⊆(V2) is fixed. We extend the complexity classification above by providing an explicit condition on (μ,F) for the problem to be tractable. In order to prove the tractability part, we generalize Hirai's theory and define a larger class of discrete convex functions. It covers, in particular, another well-known class of functions, namely submodular functions on an integer lattice. Finally, we improve the complexity of Hirai's algorithm for solving 0-Ext on orientable modular graphs.\r\n" acknowledgement: We thank the anonymous reviewers for their careful reading of our manuscript and their many insightful comments and suggestions.

This thesis summarizes three projects related to computations in TDA.\r\n\r\nThe first one establishes a variant of TDA for chromatic point sets, where each point is given a color. For example, we are given positions of cells within a tumor microenvironment, and color the cancerous cells red, and the immune cells blue.\r\n\r\nThe aim is then to give a quantitative description of how the two or more sets of points spatially interact. Building on image, kernel and cokernel variants of persistent homology, we suggest six-packs of persistent diagrams as such a descriptor.\r\n\r\nWe describe a construction of a chromatic alpha complex, which enables efficient computation of several variants of the six-packs. We give topological descriptions of natural subcomplexes of the chromatic alpha complex, and show that the radii of the simplices form a discrete Morse function. Finally, we provide an implementation of the presented chromatic TDA pipeline.\r\n\r\nThe second part aims to translate a powerful tool of sheaf theory to elementary terms using labeled matrices. The goal is to enable their use in computational settings. We show that derived categories of sheaves over finite posets have, up to isomorphism, unique objects---minimal injective resolutions---and give a concrete algorithm to compute them. We further describe simple algorithms to compute derived pushforwards and pullbacks for monotonic maps, and their proper variants for inclusions, and demonstrate their tractability by providing an implementation. Finally, we suggest a discrete definition of microsupport and show desirable properties inspired by discrete Morse theory.\r\n\r\nIn the last part, we present a collection of observations about collapses. We give a characterization of collapsibility in terms of unitriangular submatrices of the boundary matrix, a cotree-tree decomposition, and the optimal solution to a variant of the Procrustes problem. We establish relation between dual collapses and relative Morse theory and pose several open questions. Finally, focusing on complexes embedded in the three-dimensional Euclidean space, we describe a relation between the collapsibility and the triviality of a polygonal knot." acknowledgement: "The research presented in this thesis was funded with the Wittgenstein Prize,\r\nAustrian Science Fund (FWF), grant no.

A profile is an ε-Nash equilibrium if no player can gain more than ε by unilaterally deviating from their strategy. In this work, we use ε-Nash equilibria to approximate the computation of Nash equilibria. Specifically, we focus on turn-based, multiplayer stochastic games played on graphs, where players are restricted to stationary strategies - strategies that use randomness but not memory.\r\nThe problem of deciding the constrained existence of stationary Nash equilibria - where each player’s payoff must lie within a given interval - is known to be ∃ℝ-complete in such a setting (Hansen and Sølvsten, 2020). We extend this line of work to stationary ε-Nash equilibria and present an algorithm that solves the following promise problem: given a game with a Nash equilibrium satisfying the constraints, compute an ε-Nash equilibrium that ε-satisfies those same constraints - satisfies the constraints up to an ε additive error. Our algorithm runs in FNP^NP time.\r\nTo achieve this, we first show that if a constrained Nash equilibrium exists, then one exists where the non-zero probabilities are at least an inverse of a double-exponential in the input. We further prove that such a strategy can be encoded using floating-point representations, as in the work of Frederiksen and Miltersen (2013), which finally gives us our FNP^NP algorithm. \r\nWe further show that the decision version of the promise problem is NP-hard. Finally, we show a partial tightness result by proving a lower bound for such techniques: if a constrained Nash equilibrium exists, then there must be one where the probabilities in the strategies are double-exponentially small." acknowledgement: "This work is a part of project VAMOS that has received funding from the European\r\nResearch Council (ERC), grant agreement No 101020093.\r\n" alternative_title: - LIPIcs article_processing_charge: Yes arxiv: 1 author: - first_name: Ali full_name: Asadi, Ali id: 02d96aae-000e-11ec-b801-cadd0a5eefbb last_name: Asadi - first_name: Leonard full_name: Brice, Leonard last_name: Brice - first_name: Krishnendu full_name: Chatterjee, Krishnendu id: 2E5DCA20-F248-11E8-B48F-1D18A9856A87 last_name: Chatterjee orcid: 0000-0002-4561-241X - first_name: K.

Since its conceptual proposition by Charles Darwin in 1880 as an endogenous chemical signal influencing phototropism in grass, auxin has captivated scientists seeking to understand how such a small molecule exerts a profound influence on plant development.\r\nOne particularly fascinating aspect of auxin function is its ability to self-organize its transport. Through a feedback mechanism between auxin perception and directional transport—primarily mediated by PIN auxin transporters—auxin establishes narrow transport channels. This phenomenon, known as auxin canalization, is fundamental to vascular formation, regeneration, and other key developmental processes. Despite advances in our understanding, driven by experimental studies and computational models, auxin canalization remains an enigma, with many unanswered questions.\r\nLike other hormones, auxin functions through intricate signaling pathways. It operates through at least two distinct signaling mechanisms: the well-characterized canonical pathway and the less understood non-canonical pathway. While significant progress has been made in elucidating the canonical pathway, the non-canonical mechanisms remain less defined and require further investigation.\r\nIn this study, we revisit the non-canonical auxin signaling pathway mediated by the cell-surface complex Auxin Binding Protein 1-Transmembrane Kinase 1 (ABP1-TMK1), with a particular focus on its downstream phosphorylation events. We reveal that this auxin-mediated phosphorylation is conserved across the green lineage, underscoring its fundamental role in plant development. We explore key phosphorylation targets, particularly PIN2, which is essential for root gravitropism. To further understand TMK1’s role in diverse developmental processes, we identified and investigated its interactors as potential co-receptors or regulatory components within its signaling network.\r\nGiven the previously established role of ABP1-TMK1 in auxin canalization, we sought to further investigate this process and identified several TMK1 interactors also involved in this intricate mechanism.\r\nThese findings provide new insights into the complex regulation of auxin canalization, highlighting a broader and more interconnected signaling framework than previously understood." acknowledged_ssus: - _id: LifeSc - _id: Bio acknowledgement: I would like to acknowledge the facilities at ISTA, particularly LSF, IOF, and, of course, the plant facility, for providing the necessary resources for my research. alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Aline full_name: Monzer, Aline id: 2DB5D88C-D7B3-11E9-B8FD-7907E6697425 last_name: Monzer citation: ama: 'Monzer A.

The extent to which humans cooperate with each other is also an essential feature that differentiates them from other animals. Cooperation occurs even in the absence of altruistic motivations, when it is selfishly incentivised by the expectation of a future reward. For example, many economic interactions are well described that way. This kind of cooperation requires that people exhibit reciprocal behaviour that acts as a mechanism that rewards cooperation.\r\nWith game-theoretic models, it is possible to formally study potential such mechanisms and under what conditions they can exist. This thesis contributes to this effort by analysing recently introduced models of cooperation that advance on previous work by taking into account the potential for pre-existing inequality among cooperating individuals as well as the different forms that reciprocity can take.\r\nIndividuals may differ both intrinsically, in their abilities, as well as extrinsically, in the amount of resources they have available. Allowing for such differences in a model of cooperation helps to understand how inequality affects the potential for, and outcomes of, cooperation among unequals. In this thesis, it is shown that in the presence of intrinsic inequality, a similar unequal distribution of resources can increase the potential for cooperation. This effect is stronger the smaller the group is in which cooperation takes place. It is also shown that under particular assumptions, if the unequal members of a group vary the size of their contributions to a cooperative effort over time, they can thereby increase their efficiency and improve the collective outcome.\r\nCooperative behaviour in a two-person interaction can be rewarded either by direct reciprocation whenever the same two people interact again, or indirectly by a third party who observed the interaction. In the latter case of indirect reciprocity, individuals are proximally rewarded by a good reputation, which ultimately translates to being rewarded with cooperative behaviour by others. This mechanism can enable selfishly motivated cooperation even in circumstances where individuals are unlikely to meet again, akin to how money facilitates trade. While these two forms of reciprocity have mostly been studied in isolation, this thesis analyses both direct and indirect reciprocity in a general model in order to compare their relative effectiveness under different circumstances. The contribution of this thesis is an extension of previous work regarding a specific kind of interaction, whose parameters allow for convenient mathematical analysis, to the most general set of possible interactions." acknowledgement: "The research for this thesis was supported by the European Research Council\r\n(grant agreements No. 863818 and No. 850529), the European Union’s Horizon 2020 research and innovation programme (Marie Skłodowska-Curie grant agreement No. 754411),\r\nthe Austrian Science Fund (grant DOI 10.55776/COE12), the French Agence Nationale\r\nde la Recherche under the Programme d’investissements d’avenir (project reference 17-\r\nEURE-0010) and the Australian Government through the Australian Research Council\r\n(grant No. SR200100005, “Securing Antarctica’s Environmental Future”)." alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Valentin full_name: Hübner, Valentin id: 2c8aa207-dc7d-11ea-9b2f-f22972ecd910 last_name: Hübner orcid: 0009-0001-5009-4987 citation: ama: Hübner V.

in one step, one individual is replaced by a neighbor selected randomly with the influence of fitness.\r\n\r\n\r\n\r\nThe role of the networks is widely examined in the literature.\r\nThe structures that promote the spread of the desired type compared to the structureless case are called amplifiers.\r\nThe existence of amplifiers in various settings is an intensively studied topic, and in some settings, the amplifiers have been identified.\r\nMoreover, there are other important questions about the number of steps until one type spreads over the whole network (fixation time), the computational complexity, and the questions about the robustness of these processes.\r\n\r\n\r\nThis thesis explores the role of structure in evolution from many perspectives.\r\nFirst, it introduces different models and various choices that can be made in the models of evolution.\r\nIt highlights the role of the structure in the real world and how this is reflected in these models.\r\nThen, it describes the previous results and open problems.\r\nSecond, the thesis describes an amplifier for two variants of the Moran process: one with a constant birth rate and the other with a constant death rate.\r\nThis is an important contribution to the robustness of the amplification.\r\nThird, the thesis determines the complexity of spatial games.\r\nThese are processes where the fitness comes from a game, and the strength of selection is high.\r\nIt shows that determining the fate of cooperation in these games is a PSPACE-complete problem.\r\nFourth, the thesis describes the amplifier of cooperation for spatial games.\r\nThis is the first amplifier in this setting.\r\nFifth, the thesis examines the coexistence in the Moran process with environmental heterogeneity.\r\nIn this setting, the fitness depends not only on the type of the individual but also on the occupied vertex.\r\nThe chapter determines the relationship between the interactions of vertices of different types and the coexistence time.\r\nSixth, the thesis examines the social balance on networks and proposes a stochastic dynamic partially aware of the state of the graph, which reaches a balanced position quickly.\r\nFinally, the thesis presents conclusions and outlines the directions for future work.\r\n\r\n\r\n" acknowledgement: "This work was supported by the European Research Council CoG 863818 (ForMSMArt) and Austrian Science Fund 10.55776/COE12.\r\n" alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Jakub full_name: Svoboda, Jakub id: 130759D2-D7DD-11E9-87D2-DE0DE6697425 last_name: Svoboda orcid: 0000-0002-1419-3267 citation: ama: Svoboda J.
