Stable processes with reflection

Krzysztof Bogdan, Markus Kunze

We construct a Hunt process that can be described as an isotropic -stable Lévy process reflected from the complement of a bounded open Lipschitz set. In fact, we introduce a new…

Hardy perturbations of subordinated Bessel heat kernels

Krzysztof Bogdan, Tomasz Jakubowski, Konstantin Merz

Motivated by the spectral theory of relativistic atoms, we prove matching upper and lower bounds for the transition density of Hardy perturbations of subordinated Bessel heat kerne…

Positive harmonically bounded solutions for semi-linear equations

Wolfhard Hansen, Krzysztof Bogdan

For open sets in some space , we are interested in positive solutions to semi-linear equations on . Here may be an elliptic or parabolic operator of…

Yaglom limit for stable processes in cones

Krzysztof Bogdan, Zbigniew Palmowski, Longmin Wang

We give the asymptotics of the tail of the distribution of the first exit time of the isotropic -stable Lévy process from the Lipschitz cone in . We obtain the Yag…

Hardy inequalities and non-explosion results for semigroups

Krzysztof Bogdan, Bartłomiej Dyda, Panki Kim

We prove non-explosion results for Schrödinger perturbations of symmetric transition densities and Hardy inequalities for their quadratic forms by using explicit supermedian functi…

Martin kernel for fractional Laplacian in narrow cones

Krzysztof Bogdan, Bartłomiej Siudeja, Andrzej Stós

We give a power law for the homogeneity degree of the Martin kernel of the fractional Laplacian for the right circular cone when the angle of the cone tends to zero.
