报告题目: Three dimensional derived-Anosov diffeomorphisms: I: Mane's example  and Pujals-Sambarino's 'SH' condition


报告时间 2017年7月17日08:30-09:30


报告摘要  This is a series talks on the three dimensional derived-Anosov  diffeomorphisms. A three dimensional diffeomorphism is called  
derived-Anosov if it is partially hyperbolic and is in the same  isotopy class of a linear Anosov diffeomorphism $A$.

In the first talk, we recall the construction of Mane's example, and a  generalization of the construction by Pujals-Smabarino with a  condition called 'SH'.
