Query: Hochschild Cohomology of II_1 Factors with Cartan Masas   In this paper we prove that for a type II_1 factor N with a Cartan maximal
abelian subalgebra (masa), the Hochschild cohomology groups H^n(N,N)=0, for all
n \geq 1. This generalizes the result of Sinclair and Smith, who proved this
for all N having separable predual.
