Lifting Galois representations via Galois cohomology

Algebraic Geometry 2025-08-14 v1 Number Theory

Abstract

This is a survey paper, on recent progress around lifting Galois representations. I focused on approaches that solely rely on Galois cohomology. Emphasis is laid on material I talked about, at the conference held in Ottawa in June 2024, to celebrate J\'an Min\'a\v{c}'s 71th birthday.
