Two-sided estimates on the density of the Feynman-Kac semigroups of stable-like processes. (English) Zbl 1112.60059

Summary: 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.
