Explicit constructions of Galois Groups

Abstract

In this talk, I will introduce the concepts and questions arising in the explicit description of Galois groups over finite fields, and present a geometric construction based on isogeny cycles that allows for an explicit computation of Galois automorphisms. This is based on the preprint arXiv:2603.19428 (https://arxiv.org/abs/2603.19428).
