Truncated Heat Kernel and One-Loop Determinants for the BTZ Geometry
arXiv:0809.1416 · doi:10.1140/epjc/s10052-008-0743-y
Abstract
There is a special relation between the spectrum and the {\it truncated} heat kernel of the Euclidean BTZ black hole with the Patterson-Selberg zeta function. Using an orbifold description of this relation we calculate the on-shell corrections of the gravitational quantum fluctuations.
