报告摘要: In this talk, I will introduce the notion of "asymptotic expanders" defined by Li, Nowak, Spakula and myself. It generalises the classical notion of expanders, while our structure result shows that their geometry is not too far from that of expanders. I will also introduce the analytic motivation from quasi-locality, and explain applications to the coarse Baum-Connes conjecture. This is a joint work with Ana Khukhro, Kang Li and Federico Vigolo.
