Abstract: In this talk, I will introduce the notion of high dimensional expanders (expanding hypergraphs), discuss their properties and briefly discuss their applications in theoretical computer science. In the end, I will also briefly discuss the brilliant result of Kauffman and Oppenheim which shows that local expansion in hypergraphs implies global expansion.
