arXiv:0809.5179 · doi:10.1088/0264-9381/25/22/228001
Abstract
We consider complex invariants associated with compact real three-dimensional hyperbolic spaces. The contribution of the Chern-Simons invariants of irreducible U(n)-flat connections on hyperbolic fibered manifolds to the low order expansion of the quantum gravitational path integral is analyzed.
