 >Arnold diffusion in geodesic dynamics of blackholes</a>\nby Jinxin Xue/
 薛金鑫 (Tsinghua University) as part of ICCM 2020\n\n\nAbstract\nWe con
 sider the geodesics dynamics of a particle moving in a blackhole backgroun
 d that is a small perturbation of Schwarzschild and Kerr. We show that the
 re are some remarkable chaotic dynamical behaviors including Arnold diffus
 ion\, oscillatory motions and chaotic carrousel motions around the event h
 orizon. We also explain the implication of KAM in this setting\, related t
 o two observable phenomena: photon ring and QPO.\n
