Lipschitz continuity of densities of stable semigroups of measures

Volume 66 / 1993

Paweł Głowacki Colloquium Mathematicum 66 (1993), 29-47 DOI: 10.4064/cm-66-1-29-47

Abstract

In this paper we raise the question of regularity of the densities $h_t$ of a symmetric stable semigroup ${μ_t}$ of measures on the homogeneous group N under the mere assumption that the densities exist. (For a criterion of the existence of the densities of such semigroups see [11].)
