Stochastic partial differential equations on R-d are considered. The noise
is supposed to be a spatially homogeneous Wiener process. Using the theory
of stochastic integration in Banach spaces we show the existence of a Marko
vian solution in a certain weighted L-q-space. Then we obtain the existence
of a space continuous solution by means of the Da Prate, Kwapien and Zabcz
yk factorization identity for stochastic convolutions.
