Fusion categories and (2+1)-dimensional topological quantum field theory

In this talk, we are going to explore the relationship between fusion categories and (2+1)-dimensional topological quantum field theory due to Witten, Kitaev, Freedman and many others. Time permitting, I will discuss some ongoing work in collaboration with the quantum information group at USYD about boundaries between topological phases of matter in dimension 2.
