Given a finite group G we can form a category Rep(G) whose objects are representations of G, and morphisms are intertwiners. This category is far more than just a regular category, it has the structure of a symmetric category. In this talk I'll define what a symmetric category is by example, showing the interesting structure that Rep(G) possesses.
The PhD seminar is a weekly seminar held on Tuesday mornings, at 11am, for PhD students to talk about their thesis work or other projects.
There is tea in the common room afterwards.
