Abstract

In this paper, we prove the existences of pullback attractors in L^p(ℝ^N)× L²(ℝ^N) for stochastic Fitzhugh-Nagumo system driven by both additive noises and deterministic non-autonomous forcings. The nonlinearity is polynomial like growth with exponent p-1. The asymptotic compactness for the cocycle in L^p(ℝ^N)× L²(ℝ^N) is proved by using asymptotic a priori method, where the plus and minus signs of the nonlinearity at large value are not required.
