DESCRIPTION:Title: <a href="https://researchseminars.org/talk/UKVOAS/3/">E
 xpanders and generalisations</a>\nby Ana Khukhro (University of Cambridge)
  as part of UK Virtual operator algebras seminar\n\n\nAbstract\nAfter reca
 lling some motivation for studying highly-connected graphs in the context 
 of operator algebras and large-scale geometry\, we will introduce the noti
 on of "asymptotic expansion" recently defined by Li\, Nowak\, Spakula and 
 Zhang. We will explore some applications of this definition\, hopefully cu
 lminating in joint work with Li\, Vigolo and Zhang.\n\nAssumed Knowledge: 
 basic operator-algebraic concepts\, some geometric intuition\n
