No. of bitstreams: 1 carlosalbertoalmendrasmontero.pdf: 861941 bytes, checksum: 5266d3e617b3a55680988de7de3b66d5 (MD5) Previous issue date: 2014-02-25 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho, o objetivo é estudar a existência e unicidade da solução num sentido fraco para um problema não linear com valor na fronteira que é derivado de um modelo que decreve o equilibrio de um plasma confinado. Para esta finalidade se formula um problema equivalente e se estabelecem condições para este novo problema. Logo, utilizando a teoria da subdiferencial e fazendo um estudo de autovalor se consegue que este novo problema tenha solução e, além disso, seja única. / In this work, the objective is to study the existence and uniqueness of the solution in a weak sense of a nonlinear boundary value problem which it is derived from a model that describe the equilibrium of a confined plasma. For this purpose, we formulate an equivalent problem and establish conditions for this new problem. Therefore, using the theory of subdiferencial and studing an eigenvalue problem, we obtain that this new problem has a unique solution.
