Workshop III — Statistical Mechanics Beyond 2D
06 mai 2024 - 10 mai 2024 • Los Angeles, CA, États-Unis
Organisateur:
Institute for Pure and Applied Mathematics (IPAM)
Résumé:
While classical “integrable” statistical mechanics has been restricted to one and two dimensions, recent ideas have extended our understanding to (some) higher dimensional situations, or to models on non-planar graphs. These include graph limits, posets, multinomial models, random complexes and random groups, and more. While these topics are quite diverse, they nonetheless have common tools, notably the use of random walks, the graph laplacian, homology theory, and determinants. Topics will include: Benjamini-Schramm limits of graphs, unimodular measures, spanning trees and spanning complexes, chip firing/sandpile models, matroids, higher determinantal processes, random complexes, multinomial models, random groups, rigidity, and statistical physics in more than two dimensions.

Organisateur:
American Institute of Mathematics (AIM)
Résumé:
This workshop, sponsored by AIM and the NSF, will be devoted to the study of high-dimensional phenomena in discrete analysis and will touch upon themes in additive combinatorics, discrete geometry and extremal combinatorics. Each of these areas, which share many common techniques and ideas, have experienced enormous growth and seen the solution to longstanding problems in recent years. The goal of this workshop is to bring together a range of researchers with expertise in each of these areas to find common ground, start new collaborations and make progress on some of the fundamental questions in these areas.

AMS MRC conference Homotopical Combinatorics
30 jui 2024 - 06 jul 2024 • Java Center, NY, États-Unis
Organisateur:
AMS, American Mathematical Society
Résumé:
Transfer systems are a new combinatorial object that exhibit surprising connections between abstract homotopy theory, equivariant topology, and combinatorics. About ten years ago, Blumberg and Hill defined the related "indexing systems'' as the central algebraic object controlling twisted multiplications that naturally arise in the study of equivariant cohomology theories. Rubin and Balchin--Barnes--Roitzheim independently recast this notion in a much simpler framework, characterizing indexing systems in terms of transfer systems, as a particular kind of weak subposet of the lattice of subgroups of a finite group G , ordered by inclusion. Work of Ormsby--Osorno and teams of collaborators has shown how the natural generalization of this notion to an arbitrary poset has fascinating combinatorial properties, and Balchin--MacBrough--Ormsby have further connected this to abstract homotopy theories on posets. Each of these connections provides exciting results which can be transferred and reinterpreted in the other fields, yielding unexpected new structure and theorems. This MRC will introduce participants to this burgeoning new area, bringing together researchers with interests in combinatorics, algebraic topology, and abstract homotopy theory. The field is rife with open problems, including basic questions about the structure of transfer systems, combinatorics problems associated to counting transfer systems for natural families of posets, identifying connections with other combinatorial structures, and applying the language of model categories to recast and reform these questions.

AIM workshop: Graph Theory:structural properties, labelings, and connections to applications
22 jul 2024 - 26 jul 2024 • American Institute of Mathematics, Pasadena, California, États-Unis
Organisateur:
American Institute of Mathematics (AIM)
Résumé:
This workshop, sponsored by AIM and the NSF, will be devoted to current problems relating structural properties of graphs and their connections to modern applications. Specifically, we will focus on graph labelings, invariants, and the characterization of graphs with specific or extremal parameters. We will also study structural properties of families of graphs using methods such as lifts of graphs, both random and algebraic. One goal of the workshop is to unite researchers from various backgrounds in graph theory so that theoretical advancements with a potential to make an impact in applications will result. As an AWM Women in Graph Theory and Applications (WiGA)- affiliated workshop, another goal is to develop and strengthen the support of women in the graph theory community. We welcome all who support this mission.
Sujets:
The main topics for the workshop are: Graph coloring, domination, and labeling and their connections to applications. Characterizing families of graphs with extremal parameters. Generating families of graphs with desired labelings, invariants, or other structural features.

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.
