Background Fields in 2+1 Topological Gravity
arXiv:hep-th/9309078 · doi:10.1103/PhysRevD.48.3720
Abstract
The partition function of 2+1 Chern-Simons Witten topological gravity has an attractive interpretation in terms of the unbroken and broken phases of gravity. We make this physical interpretation manifest using the background field method.
