Sistemas dinâmicos e substituições /

Dutra, Aline Gobbi. January 2007 (has links)
Orientador: Ali Messaoudi / Banca: Salvador Addas Zanata / Banca: Claudio Aguinaldo Buzzi / Resumo: Uma substituicão é uma aplicação de um conjunto nito A (alfabeto) ao conjunto das palavras nitas sobre A. Neste trabalho, estudaremos propriedades topológicas e métricas dos sistemas din^amicos associados a substituicões. Em particular, mostraremos que, para uma classe de substituicões, o sistema dinâmico associado é minimal e ergódico. / Abstract: A substitution is a map from a nite set A (alphabet) to the set of nite words whose letters belong to A. In this work, we study some topological and metrical properties of the dynamical system associated to a substitution. In particular, we prove that for a class of substitutions, the associated dynamical system is minimal and ergodic. / Mestre
