No. of bitstreams: 1 3619.pdf: 885325 bytes, checksum: 7d1d94be1ebab42c4e94bfd2003c22f4 (MD5) Previous issue date: 2011-03-25 / We study non-autonomous problems with the main part given by the p- Laplacian and establish existence results of pullback attractor, comparison of solutions and existence of a maximal and a minimal complete trajectories. In bounded smooth domains we assume rather general conditions on the perturbative operator and we admit the process associated with the problem being multivalued. We obtain analogous results for systems in Rn with further restrictions in perturbative terms in such way that we deal with a univocal process. / Neste trabalho estudamos problemas não autônomos com parte principal dada pelo p-laplaciano, e estabelecemos resultados de existência de atrator no sentido pullback, comparação de soluções e a existência de duas trajetórias completas, uma maximal e outra minimal. Em domínios limitados e suaves consideramos termos perturbativos bastante gerais e admitimos que o processo associado ao problema seja multívoco. Obtivemos resultados análogos para sistemas de_nidos em todo o Rn com restrições adicionais no termo perturbativo de forma a lidarmos com um processo unívoco.
