Atratores de trajetórias para equações de evolução abstratas e aplicação a uma equação de reação difusão

Abstract

The purpose of this work is to study the asymptotic behaviour of abstract autonomous evolution equations. The first part is dedicated to the theory of existence of global attractors for univoque autonomous problems and trajectory attractors for multivoque autonomous problems. After that, we analyse the existence of the trajectory attractor for an autonomous reaction-diffusion equation for which it is not possible to guarantee the uniqueness property.
