O teorema espectral e a propriedade de \"self-adjointness\" para alguns operadores de Schrödinger / The spectral theorem and the self-adjointness property for some Schrödinger operators

Rodrigo Augusto Higo Mafra Cabral 18 December 2014 (has links)
Neste texto são demonstrados, a partir do ponto de vista da teoria dos espaços de Hilbert e da teoria das C*-álgebras, teoremas relacionados a operadores auto-adjuntos em espaços de Hilbert, entre os quais estão o Teorema Espectral, o teorema de Kato-Rellich e a desigualdade de Kato. Também são dadas aplicações destes teoremas a alguns operadores de Schrödinger provenientes da Física-Matemática. / In this text we prove, within the Hilbert spaces theory and C*-algebras points of view, some theorems which are related to self-adjoint operators acting on Hilbert spaces, among which are the Spectral Theorem, the Kato-Rellich theorem and Kato\'s inequality. Also, some applications to Schrödinger operators coming from the Mathematical-Physics context are given.
