Abstract

Let u={u(t,x);t[0,T],xRd}u=\{u(t,x);t \in [0,T], x \in {\mathbb{R}}^{d}\} be the process solution of the stochastic heat equation ut=Δu+F˙,u(0,)=0u_{t}=\Delta u+ \dot F, u(0,\cdot)=0 driven by a Gaussian noise F˙\dot F, which is white in time and has spatial covariance induced by the kernel ff. In this paper we prove that the process uu is locally germ Markov, if ff is the Bessel kernel of order α=2k,k\bN+\alpha=2k,k \in \bN_{+}, or ff is the Riesz kernel of order α=4k,k\bN+\alpha=4k,k \in \bN_{+}.
