Stationary states for stable processes with partial resetting
Tomasz Grzywny, Karol Szczypkowski, Zbigniew Palmowski +1
We study a -dimensional stochastic process which arises from a Lévy process by partial resetting, that is the position of the process at a…
L{é}vy processes: concentration function and heat kernel bounds
Tomasz Grzywny, Karol Szczypkowski
We investigate densities of vaguely continuous convolution semigroups of probability measures on . We expose that many typical conditions on the characteristic expone…
Estimates of heat kernels of non-symmetric Lévy processes
Tomasz Grzywny, Karol Szczypkowski
We investigate densities of vaguely continuous convolution semigroups of probability measures on . First, we provide results that give upper estimates in a situation…
Estimates of gradient perturbation series
Tomasz Jakubowski, Karol Szczypkowski
We give upper and lower bounds of perturbation series for transition densities, corresponding to additive gradient perturbations satisfying certain space-time integrability conditi…
