Espectro dos operadores de Schrödinger e transformações de intercâmbio de intervalos /

Artuso, Everton. January 2012 (has links)
Orientador: Ali Messaoudi / Banca: Benito Frazão Pires / Banca: Patricia Romano Cirilo / Resumo: Neste trabalho estudaremos propriedades espectrais de uma classe de operadores de Schrödinger com potencial associado a dinâmica de transfor mações de intercâmbio de inter valos, e mostraremos o resultado de Cobo-Gutierres-de Oliveira que garante que, para quase todo intercâmbio de inter valo, o espectro pontual do operador de Schrödinger asso ciado é vazio / Abstract: In this work we study the spectral properties of a class of S chrödinger operators with potentials associated with the dynamics of inter val exchange transfor mations, and we show the proof of Cobo-Gutierrez-de Oli veira of absence pure point spectrum of S chrödinger operators associated, for Lebesgue almost all inter val exchanges / Mestre
