报告摘要： 

   In 2000, G. Yu verified the coarse Baum--Connes conjecture for any metric spaces which admit a coarse embedding Hilbert spaces. However, there are counterexamples which are not coarsely embeddable into Hilbert spaces. Those counterexamples are so-called relative expanders. In a joint work with Qin Wang and Guoliang Yu, we proved the coarse Baum-Connes for a large class of relative expanders. In this talk, I will talk about the construction of relative expanders by G. Arzhantseva and R. Tessera and the strategy to prove the coarse Baum-Connes conjecture for certain relative expanders.

I am interested in the computation of the K-theory of operator algebras, especially the Baum-Connes conjecture and Novikov conjecture.
