摘要：In this talk, we first prove the existence of martingale solutions of an abstract stochastic equation with a monotone drift and a superlinear diffusion term. Both the nonlinear drift and diffusion terms are continuous but not necessarily locally Lipschitz continuous. We then apply the abstract result to establish the existence of martingale solutions of the fractional stochastic reaction-diffusion equation with a polynomial drift of any order driven by a superlinear noise. The pseudo-monotonicity techniques and the Skorokhod-Jakubowski representation theorem in a topological space are used to pass to the limit of a sequence of approximate solutions defined by the Galerkin method.
