On the first continuous $L^2$-cohomology of free group factors

Operator Algebras 2018-03-05 v2

Abstract

We prove that the first continuous L2L^2-cohomology of free group factors vanishes. This answers a question by Andreas Thom regarding continuity properties of free difference quotients and shows that one can not distinguish free group factors by means of first continuous L2L^2-Betti number.
