Properties $\Gamma $ and $L$ for type ${\rm II}\sb{1}$\ factors
1970
Proceedings of the American Mathematical Society
Using the new concept of central sequences introduced by Dixmier and Lance, it is proved that for a type Hi factor on a separable Hilbert space properties T and L are equivalent. Let (J be a countably generated type IL factor. (The referee has pointed out that this is equivalent to the existence of a faithful scalar valued trace on a.) For AEQ-let ||.<4|| denote the operator bound of A and let |.4| = [tr(^4*^4)]1/2 where tr(A) is the normalized trace on
