On the Evaluation of the Ray-Singer Torsion Path Integral
Matthias Blau, Mbambu Kakona, George Thompson
There are very few explicit evaluations of path integrals for topological gauge theories in more than 3 dimensions. Here we provide such a calculation for the path integral represe…

3 Definitions of BF Theory on Homology 3-Spheres
Matthias Blau, Mbambu Kakona, George Thompson
3-dimensional BF theory with gauge group (= Chern-Simons theory with non-compact gauge group ) is a deceptively simple yet subtle topological gauge theory. Formally, its pa…

Massive Ray-Singer Torsion and Path Integrals
Matthias Blau, Mbambu Kakona, George Thompson
Zero modes are an essential part of topological field theories, but they are frequently also an obstacle to the explicit evaluation of the associated path integrals. In order to ad…
