主讲人简介:To Fu Ma is a professor of Department of Mathematics, University of Brasília, Brazil. His research field is partial differential equations and infinite dimensional dynamical systems.

内容摘要:This talk is concerned with long-time dynamics of semilinear wave equations defined on bounded domains of R3 with cubic nonlinear terms and locally distributed damping. The existence of finite-dimensional global attractors was established by Chueshov, Lasiecka and Toundykov (2008). Here,our contribution is twofold. First, we prove uniform boundedness of attractors with respect to a external forcing parameter. Then, we study the continuity of attractors with respect to the parameter.
