Title: Ratner's measure rigidity theorem for semisimple ambient groups

Language: Chinese 

Time & Venue: 2024.11.21 10:00-11:30 MCM610

Abstract: I will give a series of lectures to explain some details of the proof of Ratner's measure rigidity theorem when the ambient group is semisimple. This is the most important and difficult case in Ratner's proof.  In the first lecture, I will give a general introduction to Ratner's theorem. I will mention several important applications of Ratner's theorem to number theory, and some important related works. I will also mention recent developments on its effective versions.
