Long Time Behavior Of Stochastic Semi-linear Degenerate Parabolic Model

In this master paper,we investigate the long-time behaviors of the stochastic semilinear degenerate parabolic equation by using Wong-Zakai approximations.Firstly,we consider the following stochastic semi-linear degenerate parabolic equation:we prove that the Wong-Zakai approximate equation has a pullback random attractor with general nonlinear functions f and ?.Then,for the following stochastic semi-linear degenerate parabolic equation with additive or multiplicative noise:andwe establish the convergence of solutions and the upper semi-continuity of random attractors as (?)?0.
