Arithmetic groups and 3-manifolds
23 mar 2020 - 27 mar 2020 • Hagen, Allemagne
Organisateur:
University of Hagen
Résumé:
Arithmetic groups provide a fruitful link between various areas, such as geometry, topology, representation theory and number theory. Methods from geometry and topology hinge on the fact that arithmetic groups are lattices in Lie groups, whereas the theory of automorphic forms establishes a connection to representation theory and number theory. This interplay is especially intriguing in the setting of hyperbolic 3-manifolds. Indeed many conjectures in 3-manifold theory tend to be much more accessible for hyperbolic 3-manifolds whose fundamental groups are arithmetic, and conversely such manifolds provide the simplest set-up in which some of the most exciting new phenomena in the Langlands program can be studied. This conference will bring together researchers with various backgrounds around links between number theory and 3-manifolds. Central topics of the conference are the cohomology of arithmetic groups, the relation between torsion and L²-torsion, profinite invariants of 3-manifolds, and number theoretic ramifications.

CIRM – Research in Pairs — Densité de Zariski et algorithmes pour groupes linéaires infinis
06 avr 2020 - 17 avr 2020 • CIRM (Marseille Luminy), France
Organisateur:
CIRM – Centre International de Rencontres Mathématiques
Résumé:
This proposal aims to develop further a novel domain of computational group theory: the design of algorithms and software for finitely generated linear groups over infinite fields. Our research is motivated by the applications of linear groups in many areas of mathematics, and the high demand for algorithms to carry out practical computations. We plan to advance our recently obtained computational techniques, based on exploring Zariski density and the strong approximation property. Specifically, we will complete the design of algorithms for isometry groups over infinite domains, and apply implementations of these algorithms to solve hard open problems via computer-aided experimentation. The latter includes experiments with symplectic hypergeometric monodromy groups. All results will be new. Moreover, the algorithms will be the first-ever of their kind, satisfying the demand for practical computational methods in the areas concerned.

Workshop on Polyhedral Products in Geometric Group Theory
25 mai 2020 - 29 mai 2020 • Montreal, Canada
Organisateur:
The Fields Institute
Résumé:
Two special cases of the polyhedral product construction have been immensely influential in geometric group theory, giving rise to at least three major families of examples of groups parametrized by flag simplicial complexes: right-angled Coxeter groups associated with the polyhedral product for pairs (,*); right-angled Artin groups associated with the polyhedral product for pairs (,*); and Bestvina-Brady groups associated with a covering space of the polyhedral product for pairs (,*). However, the interaction between toric topology and geometric group theory is largely unexplored. The purpose of this workshop is to significantly increase synergies between the two groups and establish a framework for approaching common problems and methods in a more global context.

Sub-Riemannian Geometry and Beyond, III. A gist on Lie groups in Pisa
25 mai 2020 - 29 mai 2020 • Pise, Italie
Organisateur:
Centro di Ricerca Matematica Ennio De Giorgi
Résumé:
The conference is the third meeting within prof. Le Donne's ERC project GeoMeG (Geometry of Metric Groups). The idea for the 2020 meeting is to focus on the following subjects: 1) large-scale geometry of nilpotent groups (and as the sub-Riemannian geometry appear as asymptotic cone) 2) Heintze groups (= homogeneous negatively curved manifolds) and their boundaries (which are nilpotent groups, possibly equipped with non-smooth distances) 3) geometry of solvable groups or, more generally, the large scale geometry of Lie groups. Tentative list of speakers: Manuel Amann, Marc Burger, Matias Carrasco Piaggio, Yves Cornulier, Moon Duchin, Tullia Dymarz, David Fisher, Misha Gromov, David Kyed, Grigoriy Margulis, Nicolas Monod, Pierre Pansu, Frederic Paulin, Roman Sauer, Yehuda Shalom, Xiangdong Xie, Robert Young.

Hanna Neumann Day
12 jui 2020 • Hull, Royaume-Uni
Organisateur:
University of Hull, Department of Mathematics
Résumé:
We are pleased to announce a one day conference dedicated to Hanna Neumann (1914 – 1971). It will be held at University of Hull, 12 June 2020.

Hanna Neumann was an outstanding mathematician whose research has significantly influenced the development of modern group theory. Her key achievements were in combinatorial group theory, and her book ‘Varieties of Groups’ (Springer 1967) is now a recognised classic. Hanna’s academic career was closely tied to the University of Hull, where she worked from 1946 until 1958. The conference includes lectures and a number of public events. Further details will be posted on the conference webpage.

Arithmetic Aspects of Algebraic Groups
06 sep 2020 - 11 sep 2020 • Banff, AB, Canada
Organisateur:
Banff International Research Station for Mathematical Innovation and Discovery
Résumé:
The investigation of arithmetic groups has been an active and important area of mathematical research ever since it arose in the work of Gauss, Klein, Poincare, and other famous mathematicians of the 18th and 19th centuries. New points of view have recently led to progress on classical problems, opened new directions of inquiry, and revealed unexpected connections with other areas of mathematics. The workshop will bring together experts in the area, researchers in related fields, and young mathematicians who wish to learn about the most recent advances and the most promising directions for the future of the field.

Workshop — Periods and Branching Problems for Representations of Real, p-adic and Adelic Groups
18 oct 2020 - 23 oct 2020 • Hangzhou, Chine
Organisateur:
Institute for Advanced Study in Mathematics (IASM) in Hangzhou, China, and the Banff International Research Station for Mathematical Innovation and Discovery (BIRS) in Banff, Canada
Résumé:
Symmetries appear naturally in various areas of mathematics and the sciences, ranging from geometry, numbers, differential equations to quantum mechanics. The more symmetries there are, the better we can grasp the objects by group theoretic approaches. Branching problems investigate how a large symmetries break down into smaller ones, such as fusion rules, via a mathematical formulation using the language of representations and their restrictions. Branching problems have a history of study of over 80 years. In recent years there was an outburst of research activities focus- ing on the restriction of continuous symmetries in the infinite-dimensional cases, for which new geometric and analytic methods have been developed. We highlight branching problems of infinite-dimensional representations of real, p-adic and adelic reductive groups, the former carrying analytic features and the latter carrying number-theoretic features, which might lead us to a (conjecturally) unified phenomenon. A major goal of the Workshop is to capitalize on this momentum and to gather researchers from diverse mathematical disciplines to encourage new collaborations, and achieve progress in solving open questions in number theory, geometry and physics.

Topics at the Interface of Low Dimensional Group Actions and Geometric Structures
04 jan 2021 - 15 jan 2021 • Singapore, Singapour
Organisateur:
Institute for Mathematical Sciences/National University of Singapore
Résumé:
In this two-week program, we explore the interactions between geometric group theory, geometric structures and Anosov representations. Geometric group theory, in the broadest sense, seeks to understand the structure of groups through their actions on objects with geometric meaning. Conversely, one can take a known group and attempt to understand all its geometrically meaningful actions. One natural notion that arises in this setting is an Anosov representation, which came about as an attempt to describe what it means for the action of a discrete group on a homogeneous space to be geometrically well behaved. Also, in his Erlangen program, Felix Klein viewed geometry as a space which is invariant under a group of transformations. This gave rise to the notion of a geometric structure, which gives yet another notion of a geometrically meaningful action of a group on a homogeneous space.
