报告题目:Differentiable linearization for hyperbolic and partially hyperbolic diffeomorphisms without non-resonant condition
时 间:8月2日下午3:00
地 点:理工楼631
报告摘要:We will first study the linearization problem for hyperbolic diffeomorphisms in Rn and in Banach spaces, respectively, and show that the conjugacy is differentiable at the fixed point without any non-resonant condition. Then, we further study this problem for partially hyperbolic diffeomorphisms in Rn, i.e., with center direction, and show that, without any non-resonant condition, the conjugacy is differentiable at the center manifold with a continuous derivative.
欢迎广大师生光临!
