Title:
Tensor structures for 2-representations
Speaker:
Abstract:
I will discuss the construction of tensor products of 2-representations of Lie algebras, and the extra structures (braidings, twists…) coming into play. This is aimed at constructing five dimensional topological quantum field theories categorifying the Witten-Reshetikhin-Turaev theories. as advocated by Crane and Frenkel.
