FOR DOUBLE CENTRALIZER ALGEBRAS

The double centralizer of A, denoted M(A), is the set of all pairs (T, S) where T and S are maps from A to A satisfying aT(b) = S(a)b for alla, b E A. M(A) has a C*-algebra structure and contains A as a two-sided

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. For example, (Lc;Rc) is a double ,centralizer,, where Lc(a) := ca

THE STRICT TOPOLOGY FOR DOUBLE CENTRALIZER ALGEBRASQ

1. Notation and preliminaries. Let A be a 5*-algebra. By a double centralizer on A, we mean a, pair (R, S), of, functions, from A to A such that, aR(b) = S(a)b, for a, b in A, and we will denote the set of all double centralizers on A by M (A). If (R, S) e M(A), then R and S are continuous linear operators on A …

By the double ,centralizer theorem, (recalled above) Z E(Z) = End(A) Q l, therefore it su ces to show that, for any 2End(V lA)Gal K and c2Z, we have c= c 2End(V lA): In other words, let c2End(V lA) be an element that commutes with all x2End(A) Q l, then we need to show that ccommutes with as well. Now the clever part of the argument: consider the graph of := f(v;

On double centralizer properties between quantum groups ...

If both ϕ and ψ are surjective, we call that the triple, (A,,,B,M)satisﬁes, the double centralizer property. Such double centralizer property plays a central role in many parts of algebraic Lie theory. For example, let R=C, the complex numbers ﬁeld; A=CGLm(C), the group algebra (over C) for general linear group; B=CSn, the group algebra (over C)forthe
