This book gives an exposition of the relations among the following three topics: monoidal tensor categories (such as a category of representations of a quantum

Homotopy Quantum Field Theory (HQFT) is a branch of Topological Quantum Field Theory founded by E. Witten and M. Atiyah. It applies ideas from theoretical physi
