A versão discreta da conjectura de Markus-Yamabe / The modified version of the discrete conjecture of Markus-Yamabe

Gomes, Bernardo Paschoarelli Veiga 29 March 2010 (has links)
O principal objetivo desta tese é estudar os difeomorfismos planares que satisfazem as hipóteses da Versão Modificada da Conjectura Discreta de Markus-Yamabe. Para estes difeomorfismos, definimos um conceito construtivo de número de rotação. Além disto, exibimos um contra-exemplo para a Versão Modificada da Conjectura Discreta de Markus-Yamabe que apresenta uma intersecção homoclínica transversal e implica a existência de infinitos pontos periódicos hiperbólicos / The main goal of this thesis is to study the plane diffeomorphisms satisfying the hypothesis of the Modified Version of the Discrete Conjecture of Markus-Yamabe. For these diffeomorphisms, we define a constructive concept of rotation number. Moreover, we present a counter-example to the Modified Version of the Discrete Markus-Yamabe Conjecture which exhibits a transversal homoclinic intersection, implying the existence of infinitely many hyperbolic periodic points
