"Coarse Topological Group Invariants"


Date: Mon, February 6, 2017
Time: 17:15
Place: Research II Lecture Hall

Abstract: It is hopeless to classify infinite groups up to isomorphism. There are several invariants one can use to chart the vast area inhabited by such groups. I shall discuss several numerical group invariants coming from topology, homology, and geometry:

I shall illustrate these concepts (with a focus on finiteness properites). Groups of matrices provide a good source of examples.

The colloquium is preceded by tea from 16:45 in the Resnikoff Mathematics Common Room, Research I, 127.
