Dagstuhl-Seminar — Algebraic and Analytic Methods in Computational Complexity
15 sep 2024 - 20 sep 2024 • Schloss Dagstuhl, Wadern, Allemagne
Organisateur:
Schloss Dagstuhl - Leibniz-Zentrum für Informatik
Résumé:
Computational Complexity is concerned with the resources that are required for algorithms to detect properties of combinatorial objects and structures. It has often proven true that the best way to argue about these combinatorial objects is by establishing a connection (perhaps approximate) to a more well-behaved algebraic setting. Indeed, many of the deepest and most powerful results in Computational Complexity rely on algebraic proof techniques.

DIAGRAMS 2024 — 14th International Conference on the Theory and Application of Diagrams
27 sep 2024 - 01 oct 2024 • University of Münster, Münster, Allemagne
Résumé:
Diagrams is the only conference series that provides a united forum for all areas that are concerned with the study of diagrams and has a multidisciplinary emphasis. DIAGRAMS’24 is the fourteenth conference in the series that started in 2000. The multidisciplinary nature of Diagrams means it encompasses: architecture, art, artificial intelligence, biology, cartography, cognitive science, computer science, education, graphic design, history of science, human-computer interaction, linguistics, logic, mathematics, philosophy, psychology, and software modelling. The conference attracts a large number of researchers from these interrelated fields, positioning Diagrams as the major international event in the area.

Workshop SSDW03 — Geometry, occupation fields, and scaling limits
28 oct 2024 - 01 nov 2024 • Cambridge , Royaume-Uni
Organisateur:
Isaac Newton Institute for Mathematical Sciences
Résumé:
This workshop will focus on various aspects of the geometry of interacting random paths. The aim is to bring together researchers specialising in random processes such as branching random walks, activated random walks, random interlacements, and other models of interacting random walks, as well as their continuous time counterparts. The workshop will explore questions and results concerning the geometry of the ranges of these processes, and further properties of their occupation time fields, for instance, their associated “thick points”. It will include two-mini courses in addition to the programme of research talks.

Birational Geometry and Number Theory
28 oct 2024 - 01 nov 2024 • ICMS, Bayes Centre, Edinburgh, Royaume-Uni
Organisateur:
The International Centre for Mathematical Sciences (ICMS)
Résumé:
Classifying varieties up to birational equivalence is one of the driving forces for modern research in algebraic geometry. Some of the greatest results in 20th and 21st Century algebraic geometry lie in birational geometry, with both Mori and Birkar awarded the Fields medal for their work in this area. Birational geometry has seen some very healthy and surprising interactions with number theory over the last decade.

Recent developments suggest that there is much to be gained at the interface between number theory and birational geometry, and this workshop will be one of the first attempts in the form of an international meeting to explore these interactions.

Dagstuhl-Seminar — Solving Problems on Graphs: From Structure to Algorithms
19 jan 2025 - 24 jan 2025 • Schloss Dagstuhl, Wadern, Allemagne
Organisateur:
Schloss Dagstuhl - Leibniz-Zentrum für Informatik
Résumé:
Many discrete optimization problems can be modelled as graph problems, leading to a long list of well-studied problems, which include graph partitioning, covering and packing problems, network design problems, width parameter problems, and so on. Most of these graph problems are computationally hard. However, this situation may change if we require the input to belong to some special graph class. This leads to two fundamental questions, which lie at the heart of our Dagstuhl Seminar: for which classes of graphs can a computationally hard graph problem be solved in polynomial time, and for which classes of graphs does the problem remain hard? In our seminar, we aim to discover new insights that lead to results for a whole range of problems rather than just for a single problem alone.

ACD2025 — Computational Interactions between Algebra, Combinatorics, and Discrete Geometry
10 fév 2025 - 14 fév 2025 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure & Applied Mathematics (IPAM)
Résumé:
Over the last half a century, Algebra, Combinatorics, and Discrete Geometry have undergone transformations due, in part, to the connections each of these areas have to other fields and the growth of computational approaches used in the study of theoretical mathematics. These areas are closely intertwined, with various algebraic, combinatorial, and geometric objects playing pivotal roles. These objects include monomial ideals, affine semigroup rings, Stanley-Reisner rings, Ehrhart rings, toric rings, Cox Rings, Chow Rings, Gröbner bases on the algebraic side; graphs, matroids, simplicial complexes, polytopes and polyhedral complexes, convex bodies, posets, lattices, arrangements of hyperplanes on the combinatorial and discrete geometry side.

RESEARCH IN RESIDENCE — Ky Fan type theorems, their relatives and generalizations
24 mar 2025 - 04 avr 2025 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
Combinatorial statements, such as theorems of Caratheodory, Radon, Helly, Sperner, Tucker, Ky Fan, etc., are fundamental results of combinatorial (algebraic) topology, accessible to non-specialists, which are immediately applicable to mathematical economics, data science, game theory, graph theory, mathematical optimization, computational geometry, and other fields. The aim of our project is to study the “Ky Fan correspondence » between the topology of triangulated spherical bundles and combinatorics of generalized labelings (coloring) of the associated simplicial complexes. Guided by the review of De Loera et. al. (Bull. Amer. Math. Soc., 2019) we explore the consequences of this correspondence for the envy-free and fair division problem, Tverberg-type theorems, and other related problems of topological combinatorics.

Detection, Estimation, and Reconstruction in Networks
21 avr 2025 - 25 avr 2025 • Berkeley, Californie, États-Unis
Organisateur:
Simons Laufer Mathematical Sciences Institute (SLMath)
Résumé:
In a growing number of applications, one needs to analyze and interpret data coming from massive networks. The statistical problems arising from such applications lead to important mathematical challenges: building novel probabilistic models, understanding the possibilities and limitations for statistical detection and inference, designing efficient algorithms, and understanding the inherent limitations of fast algorithms. The workshop will bring together leading researchers in combinatorial statistics, machine learning, and random graphs in the hope of cross-fertilization of ideas.
Sujets:
combinatorial statistics, random graphs, network inference, network reconstruction, detection, estimation

Frieze patterns in algebra, combinatorics and geometry
12 mai 2025 - 16 mai 2025 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
Friezes, introduced 50 years ago by Coxeter, are patterns of integers defined by a simple, local condition. They consist of a finite (or infinite) number of rows written in a lattice, starting with a row of 0s and a row of 1s and satisfying a local SL2-rule: for any four neighbours a, b, c, d forming a diamond we require ad − bc = 1. Since the discovery of links to cluster algebras of type A, a plethora of generalisations have been studied in the last decades. With this workshop, we will provide a platform to establish new links between friezes and research areas in geometry, algebra and combinatorics.
