Light PhD Seminar: Geometry, matrices and arrows

Title: Geometry, matrices and arrows

Abstract:  One of the most striking insights from category theory is that you can understand a geometric space by studying how it looks from the point of view of other spaces. We will explore this idea, and see what it says about matrix groups. Along the way we will encounter some cool ideas that have influenced different areas of mathematics over the last 100 years, see some nice pictures and hopefully have a nice time.
