Summer School on Motives and Arithmetic Groups
13 Jun 2022 - 17 Jun 2022 • Strasbourg, France
Organizer:
Institut de Recherche Mathématique Avancée de Strasbourg
Abstract:
The aim of the summer school is to provide an introduction to recent advances in the understanding of the number-theoretic content of the cohomology of arithmetic groups and of algebraic K-groups of number rings. Uncovering this information reveals deep connections with algebraic geometry, namely with the theory of motives and with motivic homotopy theory. Surprisingly, this happens even when the arithmetic groups under consideration are not directly linked with algebraic varieties.
Topics:
Mixed Tate motives, Dedekind zeta values, and polylogarithms, Weighted cohomology of Shimura varieties, Hermitian K-theory of number rings and special values of L-functions, Motivic cohomology and cohomology of arithmetic groups

Motives, quadratic forms and arithmetic — À l'occasion du 64ème anniversaire de Bruno Kahn
24 Oct 2022 - 28 Oct 2022 • Lens, France
Abstract:
Motives were originally introduced by Grothendieck in the sixties to provide a universal source to various cohomology theories of algebraic, geometric and arithmetic nature. The works of Hanamura, Levine and Voevodsky in the nineties, followed by many others, have shed a new light on the subject by introducing triangulated categories of motives and relating them to a newly defined homotopy category of schemes. More recent avatars of motives include the motives with modulus of Kahn, Miyazaki, Saito and Yamazaki or the log-motives of Binda, Park and Østvær, both purposely avoiding A1-invariance.

Computational Number Theory
27 Feb 2023 - 03 Mar 2023 • Luminy, France
Organizer:
CIRM - Jean-Morlet Chair
Abstract:
The theme of the conference will be explicit and computational methods in number theory and arithmetic geometry in a broad sense. The format will include scientific talks as well as time for informal collaboration and for coding projects related to (for example) PARI/GP, SageMath, Magma, OSCAR or the L-Functions and Modular Forms Database.

Workshop — Density Problems in Arithmetics
03 Apr 2023 - 04 Apr 2023 • Luminy, France
Organizer:
CIRM - Jean-Morlet Chair
Abstract:
ln this workshop, we will consider variants of Artin's primitive root conjecture leading to the study of the Galois groups of various radical extensions. Beyond the case of the multiplicative group studied by Lenstra and others, there are now also interesting results for elliptic radicals, and for division points in more general abelian varieties. ln this context, the elliptic analogue of Artin's conjecture is the Lang-Trotter conjecture, which is still open after more than 40 years.

RESEARCH SCHOOL — Spring school in Arithmetic Statistics
08 May 2023 - 12 May 2023 • Luminy, France
Organizer:
CIRM - Jean-Morlet Chair
Abstract:
The spring school serves an introduction to the conference "Arithmetic Statistics", and aims to provide PhD students and early stage researchers with the necessary background to enable them to fruitfully partake in the conference. lt will also be an occasion for Master students to have an introduction towards research in number theory.

Arithmetic Statistics
15 May 2023 - 19 May 2023 • Luminy, France
Organizer:
CIRM - Jean-Morlet Chair
Abstract:
The theme of the conference is a type of number theory that has become very popular over the last decades, and that is influenced by the possibility of « experimentally » studying arithmetic objects with the help of a computer. Thanks to the wide availability of computer algebra systems, essentially any number theorist nowadays has this possibility at his fingertips. There are concrete objects that are not so easily determined « by hand », such as fundamental units in number fields of higher degree, or Mordell-Weil generators of point groups of elliptic curves, and a first impression of « what these typically look like » is often obtained by numerical experimentation.
