No. of bitstreams: 1 ceilimarcolinomoreira.pdf: 628590 bytes, checksum: 89404f2fdb6f6a266713327a91a21c05 (MD5) Previous issue date: 2014-03-27 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho, apresentamos métodos envolvendo sub e supersolução para estudar a existência de solução, no sentido fraco, para três classes de problemas elípticos de segunda ordem com condição de fronteira de Dirichlet homogênea. Nos dois primeiros casos encontramos solução em W1,2 0 (Ω) e no terceiro caso encontramos solução em L1(Ω) com algumas restrições. / This paper presents methods involving sub and supersolution in order to learn the existence of weak solutions of three classes of second order elliptic problems with homogeneous Dirichlet boundary conditions. In the first two cases we find solution in W1,2 0 (Ω) and in the third case we find solution in L1(Ω) with some restrictions.
