Abstract
In the first part of this appendix we review the basics of the Chera-Simons topological quantum field theory in three dimensions and rational conformal field theory in two dimensions. The notions of Wilson lines in general three dimensional space-time and charges on a surface are briefly explained. We argue that continuous sewing of surfaces over charged punctures translates to gluings of three dimensional space-times along neighborhoods of Wilson lines. In the second part we discuss how the conditions on the physical models can be cast into a more formal axiomatic framework. We start with an outline of a few previous approaches to extended TQFT’s, and discuss their relations amongst each other. Finally, we explain how the double category picture summarizes and extends a formulation of extended TQFT’s given by Kazhdan and Reshetikhin.
