报告题目：Uniform attractors for nonclassical diffusion equations with perturbed parameter and memory

报告摘要：This talk is devoted to studying of the existence of uniform attractors for nonclassical diffusion equation with perturbed parameter and memory on a bounded domain . The main feature of this model is that the equation contains a dissipative term with perturbation parameters and the nonlinearity f satisfies the polynomial growth of arbitrary order. By using the nonclassical operator method and a new analytical method (or technique), the existence and regularity of uniform attractors generated for this equation are proved. Furthermore, we also get the upper semicontinuity of the uniform attractors when the perturbed parameter .
