Our main emphasis is on Anderson orthogonality for random Schrödinger operators. Among others, we prove that Anderson orthogonality does occur for Fermi energies in the region of complete localisation with a non-zero probability. This partially confirms recent non-rigorous findings [V. Khemani et al., Nature Phys. 11 (2015), 560–565]. The spectral shift function plays an important role in our analysis of Anderson orthogonality. We identify it with the index of the corresponding pair of spectral projections and explore the consequences thereof. All our results rely on the main technical estimate of this paper which guarantees separate exponential decay of the disorder-averaged Schatten p-norm of χa(f(H)−f(Hτ))χb in a and b. Here, Hτ is a perturbation of the random Schrödinger operator H, χa is the multiplication operator corresponding to the indicator function of a unit cube centred about a∈Rd, and f is in a suitable class of functions of bounded variation with distributional derivative supported in the region of complete localisation for H."}],"type":"journal_article","main_file_link":[{"url":"https://arxiv.org/abs/1701.02956","open_access":"1"}],"scopus_import":"1","oa_version":"Preprint","publication":"Journal of Spectral Theory","date_created":"2022-03-18T12:36:42Z","arxiv":1,"date_updated":"2026-07-06T11:54:18Z","intvolume":" 9","publication_identifier":{"issn":["1664-039X"]},"article_processing_charge":"No","department":[{"_id":"LaEr"}],"day":"01","keyword":["Random Schrödinger operators","spectral shift function","Anderson orthogonality"],"title":"Perturbations of continuum random Schrödinger operators with applications to Anderson orthogonality and the spectral shift function","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","quality_controlled":"1","_id":"10879","date_published":"2019-03-01T00:00:00Z","das_tickbox":"1","publisher":"EMS Press","acknowledgement":"M.G. was supported by the DFG under grant GE 2871/1-1.","isi":1,"doi":"10.4171/jst/267"},{"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"title":"Arithmetic and representation theory of wild character varieties","day":"01","department":[{"_id":"TaHa"}],"article_processing_charge":"No","publication_identifier":{"eissn":["1435-9855"]},"isi":1,"doi":"10.4171/JEMS/896","publisher":"EMS Press","das_tickbox":"1","quality_controlled":"1","_id":"439","date_published":"2019-10-01T00:00:00Z","year":"2019","publication_status":"published","issue":"10","volume":21,"month":"10","author":[{"orcid":"0000-0002-9582-2634","first_name":"Tamas","last_name":"Hausel","full_name":"Hausel, Tamas","id":"4A0666D8-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Mereb, Martin","id":"43D735EE-F248-11E8-B48F-1D18A9856A87","first_name":"Martin","last_name":"Mereb"},{"last_name":"Wong","first_name":"Michael","full_name":"Wong, Michael"}],"page":"2995-3052","intvolume":" 21","date_updated":"2026-07-06T11:54:39Z","arxiv":1,"project":[{"call_identifier":"FP7","name":"Arithmetic and physics of Higgs moduli spaces","_id":"25E549F4-B435-11E9-9278-68D0E5697425","grant_number":"320593"}],"scopus_import":"1","publist_id":"7384","date_created":"2018-12-11T11:46:29Z","publication":"Journal of the European Mathematical Society","oa_version":"Preprint","main_file_link":[{"url":"https://arxiv.org/abs/1604.03382","open_access":"1"}],"type":"journal_article","abstract":[{"text":"We count points over a finite field on wild character varieties,of Riemann surfaces for singularities with regular semisimple leading term.

Our approach is based on nanocontact printing and allows for the fabrication of protein patterns with feature sizes of 80 nm and periodicities down to 140 nm. This was made possible by the use of the material X-poly(dimethylsiloxane) (X-PDMS) in a two-layer stamp layout for protein printing. In a proof of principle, different proteins at various scales were printed and the pattern quality was evaluated by atomic force microscopy (AFM) and super-resolution fluorescence microscopy."}],"type":"journal_article","scopus_import":"1","date_created":"2019-02-17T22:59:24Z","publication":"Frontiers in Chemistry","oa_version":"Published Version","language":[{"iso":"eng"}],"citation":{"chicago":"Lindner, Marco, Aliz Tresztenyak, Gergö Fülöp, Wiebke Jahr, Adrian Prinz, Iris Prinz, Johann G Danzl, Gerhard J.

In bidding games, in each turn, we hold an auction between the two players to determine which player moves the token. Bidding games have largely been studied with concrete bidding mechanisms that are variants of a first-price auction: in each turn both players simultaneously submit bids, the higher\r\nbidder moves the token, and pays his bid to the lower bidder in Richman bidding, to the bank in poorman bidding, and in taxman bidding, the bid is split between the other player and the bank according to a predefined constant factor. Bidding games are deterministic games. They have an intriguing connection with a fragment of stochastic games called \r\n randomturn games. We study, for the first time, a combination of bidding games with probabilistic behavior; namely, we study bidding games that are played on Markov decision processes, where the players bid for the right to choose the next action, which determines the probability distribution according to which the next vertex is chosen. We study parity and meanpayoff bidding games on MDPs and extend results from the deterministic bidding setting to the probabilistic one.","lang":"eng"}],"has_accepted_license":"1","external_id":{"isi":["001333747500001"]},"status":"public","date_created":"2019-08-19T07:58:10Z","publication":"Proceedings of the 13th International Conference of Reachability Problems","oa_version":"Submitted Version","scopus_import":"1","type":"conference"},{"year":"2019","file_date_updated":"2020-07-14T12:47:33Z","publication_status":"published","volume":124,"month":"01","alternative_title":["LIPIcs"],"author":[{"full_name":"Pietrzak, Krzysztof Z","id":"3E04A7AA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-9139-1654","first_name":"Krzysztof Z","last_name":"Pietrzak"}],"intvolume":" 124","ddc":["000"],"date_updated":"2026-07-07T13:31:01Z","project":[{"call_identifier":"H2020","name":"Teaching Old Crypto New Tricks","_id":"258AA5B2-B435-11E9-9278-68D0E5697425","grant_number":"682815"}],"type":"conference","scopus_import":"1","oa_version":"Published Version","date_created":"2019-06-06T14:12:36Z","publication":"10th Innovations in Theoretical Computer Science Conference","external_id":{"cryptoeprintid":["2018/627"]},"has_accepted_license":"1","status":"public","abstract":[{"lang":"eng","text":"We construct a verifiable delay function (VDF) by showing how the Rivest-Shamir-Wagner time-lock puzzle can be made publicly verifiable.

A drawing of a graph on a surface is independently even if every pair of nonadjacent edges in the drawing crosses an even number of times. The Z_2-genus of a graph G, denoted by g_0(G), is the minimum g such that G has an independently even drawing on M_g. By a result of Battle, Harary, Kodama and Youngs from 1962, the graph genus is additive over 2-connected blocks. In 2013, Schaefer and Stefankovic proved that the Z_2-genus of a graph is additive over 2-connected blocks as well, and asked whether this result can be extended to so-called 2-amalgamations, as an analogue of results by Decker, Glover, Huneke, and Stahl for the genus. We give the following partial answer. If G=G_1 cup G_2, G_1 and G_2 intersect in two vertices u and v, and G-u-v has k connected components (among which we count the edge uv if present), then |g_0(G)-(g_0(G_1)+g_0(G_2))|<=k+1. For complete bipartite graphs K_{m,n}, with n >= m >= 3, we prove that g_0(K_{m,n})/g(K_{m,n})=1-O(1/n). Similar results are proved also for the Euler Z_2-genus. We express the Z_2-genus of a graph using the minimum rank of partial symmetric matrices over Z_2; a problem that might be of independent interest.

At the same time, recent work exhibits the impressive tolerance of machine learning algorithms to errors or noise arising from relaxed communication or synchronization. In this paper, we connect these two trends, and consider the following question: Can we design machine learning systems that are tolerant to network unreliability during training? With this motivation, we focus on a theoretical problem of independent interest-given a standard distributed parameter server architecture, if every communication between the worker and the server has a non-zero probability p of being dropped, does there exist an algorithm that still converges, and at what speed? The technical contribution of this paper is a novel theoretical analysis proving that distributed learning over unreliable network can achieve comparable convergence rate to centralized or distributed learning over reliable networks. Further, we prove that the influence of the packet drop rate diminishes with the growth of the number of parameter servers. We map this theoretical result onto a real-world scenario, training deep neural networks over an unreliable network layer, and conduct network simulation to validate the system improvement by allowing the networks to be unreliable."}],"arxiv":1,"date_updated":"2026-07-07T13:41:57Z"},{"_id":"10877","quality_controlled":"1","date_published":"2019-05-25T00:00:00Z","das_tickbox":"1","file":[{"content_type":"application/pdf","date_created":"2022-05-17T06:55:49Z","access_level":"open_access","creator":"dernst","relation":"main_file","file_id":"11391","file_name":"2019_EPiCs_Frehse.pdf","date_updated":"2022-05-17T06:55:49Z","success":1,"checksum":"4b92e333db7b4e2349501a804dfede69","file_size":346415}],"doi":"10.29007/rjwn","acknowledgement":"The authors gratefully acknowledge \fnancial support by the European Commission project\r\nUnCoVerCPS under grant number 643921.

In this third edition, six tools have been applied to solve five different benchmark problems in the category for piecewise constant dynamics: BACH, Lyse, Hy- COMP, PHAVer/SX, PHAVerLite, and VeriSiMPL. Compared to last year, a new tool has participated (HyCOMP) and PHAVerLite has replaced PHAVer-lite. The result is a snap- shot of the current landscape of tools and the types of benchmarks they are particularly suited for. Due to the diversity of problems, we are not ranking tools, yet the presented results probably provide the most complete assessment of tools for the safety verification of continuous and hybrid systems with piecewise constant dynamics up to this date."}],"intvolume":" 61","ddc":["000"],"date_updated":"2026-07-08T06:37:19Z","page":"1-13","alternative_title":["EPiC Series in Computing"],"author":[{"last_name":"Frehse","first_name":"Goran","full_name":"Frehse, Goran"},{"full_name":"Abate, Alessandro","last_name":"Abate","first_name":"Alessandro"},{"last_name":"Adzkiya","first_name":"Dieky","full_name":"Adzkiya, Dieky"},{"full_name":"Becchi, Anna","last_name":"Becchi","first_name":"Anna"},{"full_name":"Bu, Lei","first_name":"Lei","last_name":"Bu"},{"last_name":"Cimatti","first_name":"Alessandro","full_name":"Cimatti, Alessandro"},{"last_name":"Giacobbe","first_name":"Mirco","orcid":"0000-0001-8180-0904","id":"3444EA5E-F248-11E8-B48F-1D18A9856A87","full_name":"Giacobbe, Mirco"},{"last_name":"Griggio","first_name":"Alberto","full_name":"Griggio, Alberto"},{"last_name":"Mover","first_name":"Sergio","full_name":"Mover, Sergio"},{"first_name":"Muhammad Syifa'ul","last_name":"Mufid","full_name":"Mufid, Muhammad Syifa'ul"},{"first_name":"Idriss","last_name":"Riouak","full_name":"Riouak, Idriss"},{"full_name":"Tonetta, Stefano","first_name":"Stefano","last_name":"Tonetta"},{"first_name":"Enea","last_name":"Zaffanella","full_name":"Zaffanella, Enea"}],"volume":61,"month":"05","year":"2019","file_date_updated":"2022-05-17T06:55:49Z","publication_status":"published"},{"intvolume":" 55","arxiv":1,"date_updated":"2026-07-08T06:17:16Z","project":[{"_id":"258DCDE6-B435-11E9-9278-68D0E5697425","name":"Random matrices, universality and disordered quantum systems","call_identifier":"FP7","grant_number":"338804"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1706.08343"}],"type":"journal_article","scopus_import":"1","date_created":"2019-04-08T14:05:04Z","publication":"Annales de l'Institut Henri Poincaré, Probabilités et Statistiques","oa_version":"Preprint","external_id":{"isi":["000467793600003"],"arxiv":["1706.08343"]},"status":"public","abstract":[{"text":"For a general class of large non-Hermitian random block matrices X we prove that there are no eigenvalues away from a deterministic set with very high probability.

We compare CMB maps observed by the Planck satellite with a thousand simulated maps generated according to the ΛCDM paradigm with Gaussian distributed fluctuations. The comparison is multi-scale, being performed on a sequence of degraded maps with mean pixel separation ranging from 0.05 to 7.33°. The survey of the CMB over 𝕊2 is incomplete due to obfuscation effects by bright point sources and other extended foreground objects like our own galaxy. To deal with such situations, where analysis in the presence of “masks” is of importance, we introduce the concept of relative homology. The parametric χ2-test shows differences between observations and simulations, yielding p-values at percent to less than permil levels roughly between 2 and 7°, with the difference in the number of components and holes peaking at more than 3σ sporadically at these scales. The highest observed deviation between the observations and simulations for b0 and b1 is approximately between 3σ and 4σ at scales of 3–7°. There are reports of mildly unusual behaviour of the Euler characteristic at 3.66° in the literature, computed from independent measurements of the CMB temperature fluctuations by Planck’s predecessor, the Wilkinson Microwave Anisotropy Probe (WMAP) satellite. The mildly anomalous behaviour of the Euler characteristic is phenomenologically related to the strongly anomalous behaviour of components and holes, or the zeroth and first Betti numbers, respectively. Further, since these topological descriptors show consistent anomalous behaviour over independent measurements of Planck and WMAP, instrumental and systematic errors may be an unlikely source. These are also the scales at which the observed maps exhibit low variance compared to the simulations, and approximately the range of scales at which the power spectrum exhibits a dip with respect to the theoretical model. Non-parametric tests show even stronger differences at almost all scales. Crucially, Gaussian simulations based on power-spectrum matching the characteristics of the observed dipped power spectrum are not able to resolve the anomaly. Understanding the origin of the anomalies in the CMB, whether cosmological in nature or arising due to late-time effects, is an extremely challenging task. Regardless, beyond the trivial possibility that this may still be a manifestation of an extreme Gaussian case, these observations, along with the super-horizon scales involved, may motivate the study of primordial non-Gaussianity. Alternative scenarios worth exploring may be models with non-trivial topology, including topological defect models."}],"type":"journal_article","publication":"Astronomy & Astrophysics","date_created":"2019-08-04T21:59:18Z","scopus_import":"1","oa_version":"Published Version","month":"07","volume":627,"file_date_updated":"2020-07-14T12:47:39Z","publication_status":"published","year":"2019","author":[{"first_name":"Pratyush","last_name":"Pranav","full_name":"Pranav, Pratyush"},{"first_name":"Robert J.","last_name":"Adler","full_name":"Adler, Robert J."},{"first_name":"Thomas","last_name":"Buchert","full_name":"Buchert, Thomas"},{"id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","full_name":"Edelsbrunner, Herbert","last_name":"Edelsbrunner","first_name":"Herbert","orcid":"0000-0002-9823-6833"},{"full_name":"Jones, Bernard J.T.","last_name":"Jones","first_name":"Bernard J.T."},{"full_name":"Schwartzman, Armin","first_name":"Armin","last_name":"Schwartzman"},{"full_name":"Wagner, Hubert","id":"379CA8B8-F248-11E8-B48F-1D18A9856A87","orcid":"0009-0009-9111-8429","first_name":"Hubert","last_name":"Wagner"},{"full_name":"Van De Weygaert, Rien","last_name":"Van De Weygaert","first_name":"Rien"}],"publisher":"EDP Sciences","acknowledgement":"PP is grateful to Julian Borill from the Planck consortium for providing the data, and for the illuminating discussions and inputs.

No example of a non-sofic group is known. Higman's group, which is a circular amalgamation of four copies of the Baumslag–Solitar group, is a candidate. Here we contribute to the discussion of the problem of its soficity in two ways.\r\nWe construct variations on Higman's group replacing the Baumslag–Solitar group by other groups G. We give an elementary condition on G enjoyed for example by Z≀Z and the integral Heisenberg group, under which the resulting group is sofic.\r\n\r\nWe then use soficity to deduce that there exist permutations of Z/nZ that are seemingly pathological in that they have order dividing four and yet locally they behave like exponential functions over most of their domains. Our approach is based on that of Helfgott and Juschenko, who recently showed the soficity of Higman's group would imply some the existence of some similarly pathological functions. Our results call into question their suggestion that this might be a step towards proving the existence of a non-sofic group.","lang":"eng"}],"external_id":{"arxiv":["2406.04174"]},"status":"public","article_type":"original","citation":{"apa":"Kassabov, M., Kuperberg, V.

The colloidal SU‐8 rods are prepared by shearing an emulsion of SU‐8 polymer droplets and then exposing the resulting non‐Brownian rods to ultrasonic waves, which breaks them into colloidal rods with typical lengths of 3.5–10 µm and diameters of 0.4–1 µm. The rods are stable in both aqueous and apolar solvents, and by varying the composition of apolar solvent mixtures both the difference in refractive index and mass density between particles and solvent can be independently controlled. Consequently, these colloidal SU‐8 rods can be used in both 3D confocal microscopy and optical trapping experiments while carefully tuning the effect of gravity. This is demonstrated by using confocal microscopy to image the liquid crystalline phases and the isotropic–nematic interface formed by the colloidal SU‐8 rods and by optically trapping single rods in water. Finally, the simultaneous confocal imaging and optical manipulation of multiple SU‐8 rods in the isotropic phase is shown."}],"type":"journal_article","main_file_link":[{"url":"https://doi.org/10.1002/adma.201807514","open_access":"1"}],"oa_version":"Published Version","publication":"Advanced Materials","scopus_import":"1","date_created":"2026-06-30T06:30:50Z","language":[{"iso":"eng"}],"article_type":"original","citation":{"apa":"Fernández-Rico, C., Yanagishima, T., Curran, A., Aarts, D.
