[en] MULTIPLICATIVE ERGODIC THEOREM IN NONPOSITIVELY CURVED SPACES / [pt] TEOREMA ERGÓDICO MULTIPLICATIVO EM ESPAÇOS MÉTRICOS DE CURVATURA NÃO-POSITIVA

09 November 2021 (has links)
[pt] Apresentaremos uma versão de Teorema Ergódico Multiplicativo para cociclos subaditivos devido a Karlsson e Margulis. Como aplicação, analisaremos três exemplos de cociclos nos seguintes espaços: Grafo gerado por grupo livre em dois geradores, disco hiperbólico, espaco das matrizes positivas simétricas definidas. Também usaremos o Teorema de Karlsson e Margulis para mostrar o Teorema de Oseledets. / [en] We will show a version of Multiplicative Ergodic Theorem for subbaditive cocycles due to Karlsson and Margulis. As an application, we will analyze three examples of cocycles in following spaces: graph generated by free group of two generators, hyperbolic disc, space of positive definite symetric matrices. Also, we will use the Theorem of Karlsson and Margulis to prove Theorem of Oseledets.
