Two applications of free entropy

funct-an 2008-02-03 v2 Operator Algebras

Abstract

Using Voiculsecu's free entropy, it is shown that the free group factors L(F_n) lack property C of Popa and that they lack finite multiplicity abelian subalgebras. Property C is an assymptotic commutivity property.
