Two-sided Estimates on the Density of the Feynman-Kac Semigroups of Stable-like Processes
Renming Song, University of Illinois
Abstract
In this paper we establish two-sided estimates for the density of
the Feynman-Kac semigroups of stable-like processes with potentials
given by signed measures belonging to the Kato class. We also provide
similar estimates for the densities of two other kinds of
Feynman-Kac semigroups of stable-like processes.
