摘要:The talk will deal with the following question. Given a homeomorphism f of a surface S and a set X (of S) of fixed points of f, can one find a continuous path f_t (t\in [0,1])of homeomorphisms of S joining the identity to f, so that f_t fixes X pointwise for every t? If such a path (f_t) exist and X is maximal, then a theorem of Le Calvez allows to describe the dynamics of f. This is a joint work with Sylvain Crovisier (Université Paris-Sud) and Frédéric Le Roux (Université Pierre et Marie Curie - Paris)
内容主要是曲面的映射的不动点类,报告将不涉及特别高深的和技术细节,特别鼓励学过拓扑学的本科高年级同学参加!
