摘  要：Motivated by the famous question of M. Kac: “Can you hear the shape of a drum?”, the length spectrum rigidity problem for billiard tables has been intensively studied. In this talk, we shall first give a brief introduction on the background and recent development of this topic, and then explain a recent joint work with Vadim Kaloshin and Hong-Kun Zhang on the length spectrum rigidity for analytic Bunimovich stadia.

报告人简介：陈剑宇，苏州大学数学科学学院特聘教授。主要从事微分动力系统和光滑遍历论的理论研究，以及这些理论在弹球系统中的应用。目前在混沌与规则系统的本质共存性、部分双曲系统的混合速度估计、弹球系统的极限定理、弹球系统的长度谱刚性等方面取得了一些重要的研究成果。

欢迎各位老师同学参加！
