Algebra seminar in Lincoln: talk by Dr Tim Dokchitser

On Wednesday the 5th of December 2018 Dr Tim Dokchitser (University of Bristol) visited the Charlotte Scott Centre for Algebra in Lincoln and gave a talk  “Brauer relations”.

Abstract: “If G is a finite group, non-isomorphic G-sets X, Y may give rise to isomorphic permutation representations C[X] and C[Y]. These phenomena are called `Brauer relations’ or `linearly equivalent G-sets’, and they turn out to have interesting applications in number theory. I will explain how to classify Brauer relations in all finite groups, the history of the problem and some number-theoretic applications. This is joint work with Alex Bartel.”
