A remark on the invariants of tf*-algebras
Jun Tomiyama · Tohoku Mathematical Journal · 1958
The purpose of this paper is to supplement the theory of invariants of W*-algebras accomplished by [1], [5], [6], , [9] and [10] etc., with some considerations and to show some spatial isomorphism theorems.Through the following discussion M" denotes the center of a W*-algebra M on a Hubert space H.We denote by z(e) the central envelope of a projection e.By an isomorphism, we mean a *-preserving isomorphism.Ω denotes always the spectrum of Λf and Ω ejff the spectrum of Me.
