报告内容：
We will survey some results concerning properties of Ball quotients. Some of them are due to Ngaiming Mok and others were obtained in recent works in collaboration with Gregorio Baldi. Ball quotients are quotients of the unit ball in a finite dimensional complex vector space by a lattice. They are the only examples of hermitian locally symmetric spaces of rank 1 and Margulis’ result on arithmeticity and super-rigidity can’t be applied making their study quite challenging.
