Fractional Laplacian with supercritical killings
arxiv(2024)
摘要
In this paper, we study Feynman-Kac semigroups of symmetric α-stable
processes with supercritical killing potentials belonging to a large class of
functions containing functions of the form b|x|^-β, where b>0 and
β>α. We obtain two-sided estimates on the densities p(t, x, y) of
these semigroups for all t>0, along with estimates for the corresponding
Green functions.
