The class of forcings considered are white noise in time and coloured smooth noise in space. The existence of the dynamics in L∞, as well as the existence of an invariant measure are proven. We also show that the solutions are with high probability analytic in a strip around the real axis and give estimates on the width of that strip.enfalseInvariant measures for stochastic partial differential equations in unbounded domainstext::journal::journal article::research article
