Dr Alfonso Artigue (Universidad de la República, Uruguay) & Dr. José Vieitez (Universidad de la República, Uruguay) Datas: de 15 a 19 de fevereiro de 2016. Horário: 10:00 às 12:00hs. Sala: C-116. Ementa: Basic results: uniform expansiveness, Lyapunov functions, topology of stable sets: case of a manifold. Classification of expansive homeomorphisms on surfaces. Some aspects on greater dimension. Robust expansiveness, quasi-Anosov diffeomorphisms. Fathi's metric for expansive homeomorphisms: topological entropy of expansive homeomorphisms. Variations on the concept of expansiveness: cw-exp, h-exp, measure-exp, N-exp, countable-exp, hyper-exp. 2- expansiveness on surfaces. Robust N-expansiveness on C^r topology. Local conectedness on cwexp of surfaces. Bibliografia: Notes to be prepared by Artigue and Vieitez. N. Aoki and K. Hiraide, Topological theory of dynamical systems, North-Holland, 1994. A.
