Abstract
The aim of this project is to study evolution problems arising from semilinear equations, partial differential equations typically parabolic and hyperbolic semilinear autonomous or nonautonomous. We intend to consider semilinear partial differential equations (or nonlinear), involving an unbounded operator which is the infinitesimal generator of a C_0-semigroup (analytic or not). In the nonautonomous case, the operator will depend on the time t, instead of the explicit time dependence be just in the nonlinearity, as generally found in the literature. We will study parabolic approximations of hyperbolic problems (using fractional powers) and we try to transfer information of the parabolic problem (more generous with the class of nonlinearities) for the hyperbolic problem. In addition, we search for results of existence of pullback attractor for a parabolic plate equation as the nonlinearity has a critical growth. Additionally, we will study the existence of pullback exponential attractors for nonautonomous semilinear problems. (AU)
