# 2-Characters for finite 2-groups

**Date**: Tuesday 20 June 2017, 15:15 – 16:15**Location**: Mathematics Level 8, MALL 1, School of Mathematics**Type**: Pure Mathematics seminars, Algebra seminars, Seminar series**Cost**: Free

#### Dmitriy Rumynin, University of Warwick. Part of the algebra seminar series.

I will discuss 2-representations, i.e. actions of 2-groups on 2-vector spaces. We will focus on character theory for 2-representations. To facilitate understanding by non-specialists, my 2-group will be a group during the talk. I will indicate how the results would work for more general 2-groups.'

* After each talk at 4:15pm there will be tea/coffee in the Common Room at level 9 in Maths building. The current seminar organiser is Eleonore Faber. *
