Four dimensional topological quantum field theory, Hopf categories, and the canonical bases

arXiv:hep-th/9405183 · doi:10.1063/1.530746

Abstract

We propose a new mwthod of constructing 4D-TQFTs. The method uses a new type of algebraic structure called a Hopf Category. We also outline the construction of a family of Hopf categories related to the quantum groups, using the canonical bases.
