We introduce the notation for von Neumann algebra II-factors where is allowed to be negative. This notation is defined by rescalings of free products of II-factors, and is proved to be consistent with known results and natural operations. We also give two statements which we prove are equivalent to isomorphism of free group factors.

Abstract
We introduce the notation for von Neumann algebra II-factors where is allowed to be negative. This notation is defined by rescalings of free products of II-factors, and is proved to be consistent with known results and natural operations. We also give two statements which we prove are equivalent to isomorphism of free group factors.File in questo prodotto:
