Extremal Problems in Harmonic Analysis, Convexity, and Bellman Functions
28 Nov 2022 - 02 Dec 2022 • Providence, Rhode Island, United States
Organizer:
ICERM
Abstract:
Extremal problems in harmonic analysis recently acquired prominence in questions ranging from optimizers in Fourier restriction results to sharp geometric inequalities to sharp estimates of various singular operators of Calderón–Zygmund type. Sharp inequalities and their stability versions reveal new connections between harmonic analysis, geometric measure theory, additive combinatorics, and stochastic optimal control. There are many examples of sharp estimates by stochastic control approach and the use of special types of convexity and Monge–Ampére equation. There are interesting examples of using the computational tools in proving sharp geometric inequalities for martingales and on Hamming cube and for Fourier restriction inequalities.

AIM Workshop: Discrete and combinatorial homotopy theory
13 Mar 2023 - 17 Mar 2023 • San Jose, California, United States
Organizer:
American Institute of Mathematics (AIM)
Abstract:
This workshop, sponsored by AIM and the NSF, will be devoted to homotopy theories developed for the study of discrete and combinatorial objects. Many different models of discrete homotopy have emerged in the past 20-30 years, developed largely in isolation from one another. In this workshop, we will study different perspectives on discrete homotopy and explore their connections and differences. Among our goals is to identify important applications, particularly to combinatorics, metric geometry, and geometric group theory. We will also investigate how ideas from abstract homotopy theory (model categories, simplicial and cubical homotopy, infinity categories, etc.) may be used to extend and consolidate the theories.
Topics:
The main topics of this workshop are: A-theory of graphs and simplicial complexes; Homotopy of digraphs; Digital homotopy ; Discrete homotopy of metric spaces; Homotopy theory in topological categories; Applications of abstract homotopy theory to discrete homotopy; Applications of discrete homotopy to combinatorics, metric geometry, geometric group theory, and other areas.

Workshop — Lefschetz Properties in Algebra, Geometry, Topology and Combinatorics
15 May 2023 - 19 May 2023 • The Fields Institute, Toronto, Ontario, Canada
Organizer:
The Fields Institute
Abstract:
The study of Lefschetz properties for Artinian algebras was motivated by the Lefschetz theory for projective manifolds, begun by S. Lefschetz, and well established by the late 1950's. Many of the important Artinian graded algebras appear as cohomology rings of an algebraic variety or manifold, though recent important developments have demonstrated important cases of the Lefschetz properties beyond such geometric settings (such as Coxeter groups or matroids). This renews interest in understanding the Lefschetz property, and Artinian algebras that admit them, systematically.

AIM Workshop: From ℵ2 to infinity
15 May 2023 - 19 May 2023 • San Jose, California, United States
Organizer:
American Institute of Mathematics (AIM)
Abstract:
This workshop, sponsored by AIM and the NSF, is devoted to combinatorial problems about infinite cardinals. There are two types of infinite cardinals to investigate: successors of regular cardinals, most notably ℵ2, and successors of singular cardinals, for example ℵω+1ω+1. The workshop will focus on combinatorial principles such as the tree property, stationary reflection and the effect of consequences on forcing axioms on cardinal arithmetic, in particular what implications they have on the continuum, and the singular cardinal hypothesis (SCH).
Topics:
The main topics of the workshop are The tree property, its strengthening ITP, stationary reflection how these combinatorial principles interact with SCH; Which consequences of PFA and MM require the continuum to be ℵ2 , and more generally, their effect on cardinal arithmetic; Forcing techniques such as proper iterated forcing and Prikry type forcing.

YEP XVIII — Spectra of random graphs and related combinatorial problems
27 May 2023 - 31 May 2023 • Eindhoven, Netherlands
Organizer:
Eurandom – Workshop Centre in the area of Stochastics
Abstract:
The study of matrices with random entries started in the 1950’s and has grown into an immense body of literature until today. While the initial focus was on problems in statistical physics, in recent times random matrices have proven to be an important tool also in a variety of other fields like statistics, network analysis, image processing or machine learning. Moreover, there has been great progess in the study of matrices which arise naturally in random graphs, like the adjacency matrix, the Laplacian matrix, or the transition matrix of the random walk on the graph. The recent theoretical advances in this area are remarkable and one of the key goals of the workshop is to understand the information contained in eigenvalues and eigenvectors of high-dimensional random matrices. A second point of focus are applications of tools stemming from random graphs theory that can be used to study the spectrum of random matrices. In this workshop, we provide a platform where young and more senior researchers from the area of random matrices, random graphs and related topics can come together and exchange their research, find new collaborations and learn about different perspectives on the topic.

Model theory of valued fields
29 May 2023 - 02 Jun 2023 • CIRM (Marseille Luminy), France
Organizer:
CIRM – Centre International de Rencontres Mathématiques
Abstract:
One of the most striking recent results in model theory is Johnson’s classification, in 2020, of fields of finite dp-rank : under purely combinatorial condition (the finiteness of a certain dimension) infinite non algebraically closed fields must come with a definable henselian topology. This result illustrates (and partially explains) the very strong relationship between valuation theory and model theory that has existed since the 1960’s. Valued fields are also at the center of the interaction between model theory number theory and algebraic geometry which blossomed in the past fifteen years. This conference will bring together specialists from the algebraic, arithmetic and the pure model theory communities that all study valued fields, but with very different tools. Our aim is, by ensuring a continued dialog between these communities, to further exchanges and promote new interactions. Its main focus will be on the arithmetic of valued fields, classification and geometric model theory in valued fields and non archimedean tame geometry.

Nilpotent structures in topological dynamics, ergodic theory and combinatorics
04 Jun 2023 - 10 Jun 2023 • Będlewo, Poland
Organizer:
Banach Center
Abstract:
Classical Fourier analysis uses decompositions of functions in terms of linear phases. In recent years it was discovered that for applications in ergodic theory, combinatorics, and number theory, involving patterns such as arithmetic progressions, one has to study correlations of functions with higher order polynomial phases and other more general phases, called nilsequences, which arise from natural dynamical systems on nilmanifolds. This philosophy has helped to make progress in problems that were previously considered intractable, and has resulted in new impressive applications in the above-mentioned areas. In ergodic theory this approach is used to study the limiting behavior of multiple ergodic averages and related multiple recurrence results, in topological dynamics it has led to new structural results, and in combinatorics and number theory it is used to study patterns that can be found in sets of positive density or the set of primes. Also, very recently it has played a decisive role in progress related to the Chowla and Elliott conjectures on correlations of bounded multiplicative functions and the Mobius disjointness conjecture of Sarnak. The aim of the workshop is to introduce the above topics to a wider audience, report on recent developments, and foster collaborations and new insights.

CIMPA Research School on Graph Structure and Complex Network Analysis
04 Jun 2023 - 16 Jun 2023 • Nesin Mathematics Village, Şirince, İzmir, Türkiye
Abstract:
CIMPA Research School on Graph Structure and Complex Network Analysis will be held in Nesin Mathematics Village, Şirince, İzmir, Turkey on June 4-16, 2023. Since the works of Watts and Strogatz (1998) on one hand, and Barabási and Albert (1999) on the other, graph theory has become a major mathematical field that provides a framework to handle network properties theoretically and enables us with very powerful tools to model and solve problems on networks. Understanding their graph structure is a key point in deriving efficient algorithms in large networks. In this school, we will cover theoretical aspects of graph structure analysis as well as applications on complex network studies.

BIRS Workshop — Isogeny Graphs in Cryptography
20 Aug 2023 - 25 Aug 2023 • Banff, Alberta, Canada
Organizer:
Banff International Research Station (BIRS) for Mathematical Innovation and Discovery
Abstract:
Despite the enormous commercial potential that quantum computing presents, the existence of large-scale quantum computers also has the potential to destroy current security infrastructures. Post-quantum cryptography aims to develop new security protocols that will remain secure even after powerful quantum computers are built. This workshop focuses on isogeny-based cryptography, one of the most promising areas in post-quantum cryptography. In particular, we will examine the security, feasibility and development of new protocols in isogeny-based cryptography, as well as the intricate and beautiful pure mathematics of the related isogeny graphs and elliptic curve endomorphism rings. To address the goals of both training and research, the program will be comprised of keynote speakers and working group sessions.
