本文研究了环和代数中与中心化子有关的恒等式。例如,我们证明了以下结果。设A是半单H*-代数,T:A→A是满足关系T(xm+n+1)=xmt(X)xn的加性映射,对所有x∈A和一些整数m≥1,n≥1,在这种情况下T是左和右中心子.
In this paper we investigate identities related to centralisers in rings and algebras. We prove, for example, the following result. Let A be a semisimple H* -algebra and let T: A → A be an additive mapping satisfying the relation T(xm+n+1) = xmT(x)xn for all x ∈ A and some integers m ≥ 1, n ≥ 1. In this case T is a left and a right centraliser.
