The conference will focus on the recent developments in arithmetic geometry, its applications and explicit and computational methods in approaching the relevant problems. There will be four main axes around which all talks will be organised: Automorphic forms and moduli spaces; Galois representations: geometric and constructive, modularity; Rational points and obstructions; Effective methods in arithmetic geometry. Leading experts in the field have accepted to contribute to the conference, making it a particularly interesting event.
La conférence se concentrera sur les développements récents en géométrie arithmétique, ses applications et les méthodes explicites et computationnelles pour aborder les problèmes pertinents. Il y aura quatre axes principaux autour desquels toutes les présentations seront organisées : Formes automorphes et espaces de modules ; Représentations galoisiennes : géométriques et constructives, modularité ; Points rationnels et obstructions ; Méthodes efficaces en géométrie arithmétique. Des experts de premier plan dans ce domaine ont accepté de contribuer à la conférence, ce qui en fait un événement particulièrement intéressant.
The conference is dedicated to the memory of Bas Edixhoven (Professor, Leiden University)
