Senior Lecturer in Mathematics, Dr Constanze Roitzheim, represented the School at the 34th British Topology Meeting held at the University of Warwick on 16 – 18 September. Constanze’s talk was the first of the day on Tuesday 17 September and was entitled **Equivariant homotopy commutativity, trees and chicken feet**.

As she explained:

“Commutativity up to homotopy can be daunting, and it gets even more difficult to track when equivariant structures get introduced. In the case of a finite group, however, the options for equivariant homotopy commutativity can be encoded using simple combinatorics…”. Her talk included relevant examples.
