Title: Quasitraces on exact C*-algebras are traces
Abstract: Last talk, we discussed Kaplansky's conjecture of whether quasitraces are traces. In this talk, we shall look at the proof of the best known partial answer to this conjecture, namely Haagerup's theorem that the conjecture holds true on exact C*-algebras.
