Each player simultaneously says \"Heads\" or \"Tails\". The team wins if all four choices match; otherwise the Devil wins. If all team players randomise independently, they win with probability 1/8; if all players share a common source of randomness, they win with probability 1/2. What happens when each pair of team players shares a source of randomness? Can the team do better than win with probability 1/4? The surprising (and nontrivial) answer is yes!\r\nWe introduce Dicey Games, a formal framework motivated by the study of distributed systems with shared sources of randomness (of which the above example is a specific instance).

It is possible to manipulate these quantities without altering the geometric appearance of an object by introducing cavities in its interior. Algorithms that find cavities of suitable shapes and sizes have enabled the computational design of spinning tops, yo-yos, wheels, buoys, and statically balanced objects. Previous work is based, for example, on topology optimization on voxel grids, which introduces a large number of optimization variables and box constraints, or offset surface computation, which cannot guarantee that solutions to a feasible problem will always be found.\r\n\r\nIn this work, we provide a mathematical analysis of constrained topology optimization problems that depend only on mass moments. This class of problems covers, among others, all applications mentioned above. Our main result is to show that no matter the outer shape of the rigid body to be optimized or the optimization objective and constraints considered, the optimal solution always features a quadric-shaped interface between material and cavities. This proves that optimal interfaces are always ellipsoids, hyperboloids, paraboloids, or one of a few degenerate cases, such as planes.\r\n\r\nThis insight lets us replace a difficult topology optimization problem with a provably equivalent non-linear equation system in a small number (<10) of variables, which represent the coefficients of the quadric. This system can be solved in a few seconds for most examples, provides insights into the geometric structure of many specific applications, and lets us describe their solution properties. Finally, our method integrates seamlessly into modern fabrication workflows because our solutions are analytical surfaces that are native to the CAD domain.","lang":"eng"}],"author":[{"last_name":"Hafner","first_name":"Christian","id":"400429CC-F248-11E8-B48F-1D18A9856A87","full_name":"Hafner, Christian"},{"last_name":"Ly","full_name":"Ly, Mickaël","id":"6340d7f0-b48d-11eb-b10d-b7487e71d9f1","first_name":"Mickaël"},{"last_name":"Wojtan","id":"3C61F1D2-F248-11E8-B48F-1D18A9856A87","full_name":"Wojtan, Christopher J","first_name":"Christopher J","orcid":"0000-0001-6646-5546"}],"keyword":["Topology Optimization","Mass Moments","Computational Geometry"],"corr_author":"1","das_tickbox":"0","isi":1,"article_number":"78","publication":"Transactions on Graphics","conference":{"start_date":"2024-07-28","end_date":"2024-08-01","location":"Denver, Colorado"},"status":"public","_id":"17203","month":"07","year":"2024","article_processing_charge":"Yes (via OA deal)","oa":1,"scopus_import":"1","title":"Spin-it faster: Quadrics solve all topology optimization problems that depend only on mass moments","ddc":["516"],"fulldoi":"https://doi.org/10.1145/3658194","file_date_updated":"2024-07-17T09:29:13Z","doi":"10.1145/3658194","publisher":"Association for Computing Machinery","publication_identifier":{"eissn":["1557-7368"],"issn":["0730-0301"]},"day":"01"},{"keyword":["surface tracking","topology change","non- manifold meshes","multi-material flows","solid modeling"],"OA_type":"hybrid","das_tickbox":"0","isi":1,"corr_author":"1","article_number":"54","abstract":[{"lang":"eng","text":"We introduce a multi-material non-manifold mesh-based surface tracking algorithm that converts self-intersections into topological changes.

Because the criteria are easily verified in such a setting, they are expected to be of general use."}],"author":[{"full_name":"Boissonnat, Jean-Daniel","first_name":"Jean-Daniel","last_name":"Boissonnat"},{"last_name":"Dyer","first_name":"Ramsay","full_name":"Dyer, Ramsay"},{"full_name":"Ghosh, Arijit","first_name":"Arijit","last_name":"Ghosh"},{"full_name":"Wintraecken, Mathijs","id":"307CFBC8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7472-2220","first_name":"Mathijs","last_name":"Wintraecken"}],"keyword":["Computational Theory and Mathematics","Discrete Mathematics and Combinatorics","Geometry and Topology","Theoretical Computer Science"],"isi":1,"corr_author":"1"},{"author":[{"last_name":"Lampart","first_name":"Jonas","full_name":"Lampart, Jonas"},{"last_name":"Mitrouskas","full_name":"Mitrouskas, David Johannes","id":"cbddacee-2b11-11eb-a02e-a2e14d04e52d","first_name":"David Johannes"},{"last_name":"Mysliwy","id":"316457FC-F248-11E8-B48F-1D18A9856A87","full_name":"Mysliwy, Krzysztof","first_name":"Krzysztof"}],"abstract":[{"text":"For the Fröhlich model of the large polaron, we prove that the ground state energy as a function of the total momentum has a unique global minimum at momentum zero.

A partial triangulation of P is a full triangulation of some subset P′ of P containing all extreme points in P. A bistellar flip on a partial triangulation either flips an edge (called edge flip), removes a non-extreme point of degree 3, or adds a point in P∖P′ as vertex of degree 3. The bistellar flip graph has all partial triangulations as vertices, and a pair of partial triangulations is adjacent if they can be obtained from one another by a bistellar flip. The edge flip graph is defined with full triangulations as vertices, and edge flips determining the adjacencies. Lawson showed in the early seventies that these graphs are connected. The goal of this paper is to investigate the structure of these graphs, with emphasis on their vertex connectivity. For sets P of n points in the plane in general position, we show that the edge flip graph is ⌈n/2−2⌉-vertex connected, and the bistellar flip graph is (n−3)-vertex connected; both results are tight. The latter bound matches the situation for the subfamily of regular triangulations (i.e., partial triangulations obtained by lifting the points to 3-space and projecting back the lower convex hull), where (n−3)-vertex connectivity has been known since the late eighties through the secondary polytope due to Gelfand, Kapranov, & Zelevinsky and Balinski’s Theorem. For the edge flip-graph, we additionally show that the vertex connectivity is at least as large as (and hence equal to) the minimum degree (i.e., the minimum number of flippable edges in any full triangulation), provided that n is large enough. Our methods also yield several other results: (i) The edge flip graph can be covered by graphs of polytopes of dimension ⌈n/2−2⌉ (products of associahedra) and the bistellar flip graph can be covered by graphs of polytopes of dimension n−3 (products of secondary polytopes). (ii) A partial triangulation is regular, if it has distance n−3 in the Hasse diagram of the partial order of partial subdivisions from the trivial subdivision. (iii) All partial triangulations of a point set are regular iff the partial order of partial subdivisions has height n−3.

A classic example is the joint convexity of the quantum relative entropy which is equivalent to the Data Processing Inequality. The latter says that quantum operations can never increase the relative entropy. The monotonicity versions often have many advantages, and often have direct physical application, as in the example just mentioned. Moreover, the monotonicity results are often valid for a larger class of maps than, say, quantum operations (which are completely positive). In this paper we prove several new monotonicity results, the first of which is a monotonicity theorem that has as a simple corollary a celebrated concavity theorem of Epstein. Our starting points are the monotonicity versions of the Lieb Concavity and the Lieb Convexity Theorems. We also give two new proofs of these in their general forms using interpolation. We then prove our new monotonicity theorems by several duality arguments.","lang":"eng"}],"publication_identifier":{"issn":["0024-3795"]},"day":"01","ddc":["510"],"fulldoi":"https://doi.org/10.1016/j.laa.2022.09.001","doi":"10.1016/j.laa.2022.09.001","file_date_updated":"2023-01-27T08:08:39Z","publisher":"Elsevier","article_processing_charge":"Yes (via OA deal)","oa":1,"scopus_import":"1","title":"Monotonicity versions of Epstein's concavity theorem and related inequalities","publication":"Linear Algebra and its Applications","_id":"12216","status":"public","month":"12","year":"2022","citation":{"ieee":"E.

A central stepping stone toward realizing this promise is the demonstration of multifunctionality under several constraints (e.g., at multiple incident wavelengths and/or angles) in a single device, an achievement being hampered by design limitations inherent to single-layer planar geometries. Here, we propose a framework for the inverse design of multilayer metaoptics via topology optimization, showing that even few-wavelength thick devices can achieve high-efficiency multifunctionality, such as multiangle light concentration and plan-achromaticity. We embody our framework in multiple closely spaced patterned layers of a low-index polymer, with fabrication constraints specific to this platform enforced in the optimization process. We experimentally demonstrate our approach with an inverse-designed 3D-printed light concentrator working at five different nonparaxial angles of incidence. Our framework paves the way toward realizing multifunctional ultracompact 3D nanophotonic devices.","lang":"eng"}],"author":[{"first_name":"Charles","full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","last_name":"Roques-Carmes"},{"last_name":"Lin","full_name":"Lin, Zin","first_name":"Zin"},{"full_name":"Christiansen, Rasmus E.","first_name":"Rasmus E.","last_name":"Christiansen"},{"last_name":"Salamin","full_name":"Salamin, Yannick","first_name":"Yannick"},{"full_name":"Kooi, Steven E.","first_name":"Steven E.","last_name":"Kooi"},{"last_name":"Joannopoulos","first_name":"John D.","full_name":"Joannopoulos, John D."},{"last_name":"Johnson","first_name":"Steven G.","full_name":"Johnson, Steven G."},{"last_name":"Soljačić","first_name":"Marin","full_name":"Soljačić, Marin"}],"keyword":["metasurfaces","inverse design","multilayered metaoptics","3D printing","topology optimization"],"OA_type":"green"},{"project":[{"_id":"62796744-2b32-11ec-9570-940b20777f1d","name":"Random matrices beyond Wigner-Dyson-Mehta","grant_number":"101020331","call_identifier":"H2020"}],"volume":10,"acknowledgement":"J.H. acknowledges partial financial support by the ERC Advanced Grant ‘RMTBeyond’ No. 101020331.

We prove that for any Hausdorff compactum X with a free action of the symmetric group Sn, there exists an Sn-equivariant map X→Rn whose image avoids the diagonal {(x,x,…,x)∈Rn∣x∈R}. Previously, the special cases of this statement for certain X were usually proved using the equivartiant obstruction theory. Such calculations are difficult and may become infeasible past the first (primary) obstruction. We take a different approach which allows us to prove the vanishing of all obstructions simultaneously. The essential step in the proof is classifying the possible degrees of Sn-equivariant maps from the boundary ∂Δn−1 of (n−1)-simplex to itself. Existence of equivariant maps between spaces is important for many questions arising from discrete mathematics and geometry, such as Kneser’s conjecture, the Square Peg conjecture, the Splitting Necklace problem, and the Topological Tverberg conjecture, etc. We demonstrate the utility of our result applying it to one such question, a specific instance of envy-free division problem.","lang":"eng"}]},{"publication_status":"published","department":[{"_id":"HeEd"}],"date_updated":"2025-04-14T07:43:50Z","article_type":"original","file":[{"file_id":"9795","checksum":"c848986091e56699dc12de85adb1e39c","relation":"main_file","date_updated":"2021-08-06T09:52:29Z","success":1,"content_type":"application/pdf","file_name":"2021_DescreteCompGeopmetry_Boissonnat.pdf","file_size":983307,"creator":"kschuh","date_created":"2021-08-06T09:52:29Z","access_level":"open_access"}],"tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"intvolume":"        66","quality_controlled":"1","oa_version":"Published Version","date_created":"2020-12-12T11:07:02Z","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","language":[{"iso":"eng"}],"date_published":"2021-07-01T00:00:00Z","has_accepted_license":"1","type":"journal_article","ec_funded":1,"issue":"1","external_id":{"isi":["000597770300001"]},"citation":{"short":"J.-D.
