CUBIC DOUBLE CENTRALIZERS AND CUBIC MULTIPLIERS
CUBIC DOUBLE CENTRALIZERS AND CUBIC MULTIPLIERS

A is said to be left ,centralizer, on A if L(ab) = L(a)b for all a;b 2 A. Similarly, a linear mapping R: A ! A that R(ab) = aR(b) for all a;b 2 A is called right ,centralizer, on A. A ,double centralizer, on A is a pair (L;R), where L is a left ,centralizer,, R is a right ,centralizer, and aL(b) = R(a)b for all a;b 2 A.

The double centralizer theorem deals with situations where equality occurs. If S is an additive subgroup of a Lie ring A, then N A (S) is the largest Lie subring of A in which S is a Lie ideal. If S is a Lie subring of a Lie ring A, then S⊆N A (S). See also. Commutant; Stabilizer subgroup; Multipliers and centralizers (Banach spaces) Double centralizer theorem

By Müger's ,double centralizer theorem, and Lemma 3.11, it suffices to show that ⁠. By [ 11 , Proposition 6.7], the simple objects (up to isomorphism) of are given by the set In the second equality above we used Lemma 4.10, and in the third equality we used Note 3.5.

Theorem, 10. Let be a -algebra and be a -mapping. Then is a -algebra if and only if is an isometry. Proof. Let be a -algebra. Then, by ,Theorem, 8, (ii), is an isometry. For the converse, by Lemma 1, is a multiplier and, is a ,double centralizer,. So, by ,Theorem, 9, is a -algebra.

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 ...
