Gauge fixing and equivariant cohomology
arXiv:hep-th/0505241 · doi:10.1088/0264-9381/22/19/018
Abstract
The supersymmetric model developed by Witten to study the equivariant cohomology of a manifold with an isometric circle action is derived from the BRST quantization of a simple classical model. The gauge-fixing process is carefully analysed, and demonstrates that different choices of gauge-fixing fermion can lead to different quantum theories.
