Variational solutions and random dynamical systems to SPDEs perturbed by fractional gaussian noise

Abstract

This paper deals with the following type of stochastic partial differential equations (SPDEs) perturbed by an infinite dimensional fractional Brownian motion with a suitable volatility coefficient Φ: d X (t) = A (X (t)) d t + Φ (t) d B H (t), where A is a nonlinear operator satisfying some monotonicity conditions. Using the variational approach, we prove the existence and uniqueness of variational solutions to such system. Moreover, we prove that this variational solution generates a random dynamical system. The main results are applied to a general type of nonlinear SPDEs and the stochastic generalized p -Laplacian equation. © 2014 Caibin Zeng et al.
