ABSTRACTS Workshop on “Higher topological quantum field theory
... There is a scarcity of four-dimensional topological state sum models. Apart from the Crane-Yetter model, defined in the 90s, little is known. In this talk, a family of invariants of four-dimensional manifolds is presented. Some of them are stronger than the signature and Euler invariant. The invaria ...
