Densities for piecewise deterministic Markov processes with boundary
Piotr Gwiżdż, Marta Tyran-Kamińska
We study the existence of densities for distributions of piecewise deterministic Markov processes. We also obtain relationships between invariant densities of the continuous time p…

Positive semigroups and perturbations of boundary conditions
Piotr Gwiżdż, Marta Tyran-Kamińska
We present a generation theorem for positive semigroups on an space. It provides sufficient conditions for the existence of positive and integrable solutions of initial-bound…
