Abstract

In this talk, I will discuss profinite properties of Artin groups, such as residual finiteness, and the connection between the group and its profinite completion. Informally, those properties tell us if the geometry and the algebra of the group can be approximated by its finite quotients. I will discuss some of my contributions, including joint work with Kevin Schreve.
