报告题目：Dynamics of stochastic nonlocal reaction- diffusion equations driven by multiplicative noise

报告摘要：In this talk, it mainly deals with a kind of  fractional stochastic nonlocal partial differential equations driven by multiplicative noise. We first prove the existence and uniqueness of solutions to this kind of equations with white noise by applying the Galerkin method. Then, the existence and uniqueness of tempered pullback random attractors for the equations are ensured in an appropriate Hilbert space. When the fractional nonlocal partial differential equations are driven by colored noise, which indeed are approximations of the previous ones, we show the convergence of solutions of Wong–Zakai approximations and the upper semicontinuity of random attractors of the approximate random system as δ → 0.
