1. Taxa de convergência de atratores de algumas equações de reação-difusão perturbadas. / Rate of convergence of attractors de some reaction-difusion equations pertubadas
In this work we study the asymptotic nonlinear dynamical of some reaction-diffusion parabolic equations under perturbations in parameter and singular perturbations in a dumbbell domain. More precisely, we treat of the attractors from these problems, we seek understand the dependence these asymptotic set of states in relationship the parameter, investigating

2. Atratores para uma classe de equações de vigas extensíveis fracamente dissipativas / Attractors for a class of equations of extensible beams weakly dissipative
This work contains some results on the existence, uniqueness and asymptotic behavior of solutions for a nonlinear beam equation of Kirchhoff type, u IND. tt+ DELTA POT. 2u+ M(INT. IND.|u| 2 dx) u + g(u IND. t) + f (u) = h; where R POT. Nis a bounded domain with smooth boundary . This equation is a model for small vibrations of extensible beams. The nonlocal

3. Atratores para sistemas dinâmicos discretos: dimensão fractal e continuidade da estrutura por perturbações / Discrete dynamical systems attractors: fractal dimension and continuity of the structure under perturbations
In this work, we study a generalization of gradient discrete semigroups, the gradientlike semigroups, some of its properties and its invariance under small perturbations; that is, small perturbations of gradient-like semigroups are still gradient-like semigroups. As a consequence of the characterization of the attractors for this sort of semigroups, we study
