Title: Torsion primes in modular representation theory

Abstract: The recent quite unexpected appearance of torsion primes in the representation theory of modular algebraic groups by G. Williamson provides new challenges for representation theorists, some of them of number theoretic nature. I'd like to give an overview on the torsion prime problem and propose a new approach that translates the problem into a categorical framework in terms of (elementary) sheaf theory on partially ordered spaces.
