# Set theory and C*-algebras

Boise Set Theory Seminar, Boise, December 2012

*Abstract*: Operator algebras is an area of analysis where set theory has had a lot of impact in recent years. Corona algebras are a kind of quotient C*-algebra that are closely related to quotient structures found in set theory like P($\omega$)/Fin. In this talk I’ll introduce these terms, and then present some work of (and together with) Ilijas Farah on outer automorphisms of corona algebras.
