Abstract We consider a parabolic stochastic partial differential equation (SPDE) on 0, 1 that is forced with multiplicative space-time white noise with a bounded and Lipschitz diffusion coefficient and a drift coefficient that is locally Lipschitz and satisfies an L L L log L growth condition. We prove that the SPDE is well posed when the initial data is in L²0, 1 L 2 0, 1. This solves a strong form of an open problem.
