短课程题目： Integrability and rigidity for convex billiard
报告人： Professor Vadim Kaloshin (University of Maryland & IST Austria)
报告摘要： The main topic of the minicourse is dynamics of Bikhoff billiards or billiards in convex bounded regions.
Motivated by the famous question Can you hear the shape of a drum? We shall discuss several notions of
deformational spectral rigidity for convex billiards. It turns out that techniques to study these notions are also
applicable to perturbative Birkhoff Conjecture about integrable billiards.
