Abstract
We obtain an explicit formula of the Bergman kernel for Hartogs domains over bounded homogeneous domains. In order to find a simple formula, we consider a Siegel domain biholomorphic to the bounded homogeneous domain and use its Bergman kernel obtained by Gindikin. The Bergman kernel of the Hartogs domain is expressed by two different forms and the main part of the Bergman kernel is a polynomial whose coefficients contain the Stirling number of the second kind. As an application of our formula, we investigate the Lu Qi-Keng problem for our Hartogs domains and give some important examples of Hartogs domains whose Bergman kernels are zero-free.
