Jeffrey Morton (U Hamburg):

Abstract: I will describe a general construction which gives ”extended” Topological Quantum Field Theories (ETQFT) in codimension 2 from a gauge group, using a quantization functor in the spirit of Freed-Hopkins-Lurie-Teleman. I will discuss prospects for a generalization of this method to a codimension-3 ETQFT higher gauge theory based on categorical groups, and beyond.
