Abstract
We prove an exact formula for the Bergman kernel function of hyperbolic Riemann surfaces either of finite topology or of positive injectivity radius. The formula involves summation over all geodesic loops based at a point, which has a striking analogy with the Selberg trace formula. As an application, we prove a result about the maximum and minimum of the Bergman kernel function. We also prove an estimate of the off-diagonal Bergman kernel.
