double centralizer property, there exists an a & R such that ¢ ( u) = au for all u £ U. Let us set fb'(w) = fb(w) - aw for wE W. Then fb'(w) = 0 if w E u. Our proof would be complete if we can show that ¢'(v) = 0 , for v E V also. We have two cases to consider. Case I :- V = v1, i.e. U generates V.

Topological Measure Theory for Double Centralizer Algebras

FOR ,DOUBLE CENTRALIZER, ALGEBRAS BY ROBERT A. FONTENOT(1) ABSTRACT. The classes of tight, r-additive, and a-additive linear functionals on the ,double centralizer, algebra of a C*-algebra A are defined. The algebra A is called measure compact if all three classes coincide. Sev-eral theorems relating the existence of certain types of approximate ...

Theorem 2.31, so Hom,(D/T(A), IV) = 0 by [lo, Lemma 2.11. It follows that Hom,(C/a(A), W) = 0 and Hom,(C/o(A), V) = 0. Therefore Hom,(C/a(A), M) = 0 in view of (*), i.e., ,M is of type Fh . Serial rings are not necessarily Morita equivalent to direct sums of local rings.
