Qli'-1 RINGS

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.

the ,Double Centralizer Theorem, to obtain dimQ A ≤ dimQ A1 dimQ A2 ≤ dimQ A1 dimQ CenA(A1) = dimQ A. and conclude that A ≃ A1 ⊗A2. Let Li be a maximal subﬁeld of Ai (i = 1,2). Then L0 = L1 ⊗ L2 is a maximal subﬁeld of A. Let Gi = Li ∩ (H1 × H2), (i = 0,1,2). We claim that G0 = G1G2. The inclusion G1G2 ⊂ G0 is obvious.

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 ...

Completion by Derived Double Centralizer - arxiv-vanity.com

Let A be a commutative ring, and let a be a weakly proregular ideal in A. (If A is noetherian then any ideal in it is weakly proregular.) Suppose M is a compact generator of the category of cohomologically a-torsion complexes. We prove that the derived ,double centralizer, of M is isomorphic to the a-adic completion of A. The proof relies on the MGM equivalence from [PSY] and on derived Morita ...
