"Nerve"-Racking Topology


The concept of a nerve, a simplicial complex formed from a family of objects by taking sets that have nonempty intersections, comes up in various guises in mathematics. In this talk, I will address two such applications that relate to topology: the nerve of a cover, used to calculate Cech homology, and Segal's nerve of a topological group, used to construct classifying spaces.
