Markov property and path regularity for the solutions to SPDEs driven by cylindrical-martingale valued measures

Abstract

In this paper we prove the Markov property for the solution to stochastic partial differential equations driven by a cylindrical orthogonal martingale-valued measure. We assume our coefficients are time-dependent and satisfy some growth and Lipschitz conditions. We also prove that for time-independent coefficients and under mild assumptions on the cylindrical orthogonal martingale-valued measure, the solutions to our stochastic partial differential equations are Feller. Finally, in the case that the $C_0$-semigroup is quasi-contraction, we show that the solution to our stochastic partial differential equation possesses a cà dlà g version.
