Abstract

We consider a pp-Laplace evolution problem with stochastic forcing on a bounded domain DRdD\subset\mathbb{R}^d with homogeneous Dirichlet boundary conditions for 1<p<1<p<\infty. The additive noise term is given by a stochastic integral in the sense of It\^{o}. The technical difficulties arise from the merely integrable random initial data u0u_0 under consideration. Due to the poor regularity of the initial data, estimates in W01,p(D)W^{1,p}_0(D) are available with respect to truncations of the solution only and therefore well-posedness results have to be formulated in the sense of generalized solutions. We extend the notion of renormalized solution for this type of SPDEs, show well-posedness in this setting and study the Markov properties of solutions.
