Title：Integrability of Birkhoff Billiard Tables
Abstract：This talk will be on integrability of Birkhoff billiards. The famous Birhkhoff conjecture claims that all the integrable billiard systems are those induced by ellipses. I will discuss some recent progresses in the study of Birhkhoff conjecture. The talk is based on the joint works with Vadim Kaloshin and Alfonso Sorrentino.
