A Result Concerning Additive Mappings in Semiprime Rings
-
Maja Fos̆ner
Abstract
In this paper we prove the following result. Let R be a 2-torsion free semiprime ring and let f : R → R be an additive mapping satisfying the relation f(x)x2 + x2f(x) = 0 for all x ∈ R. In this case f = 0. Any semisimple Banach algebra (for example, C* algebra) is semiprime. Therefore this algebraic result might be of some interest from functional analysis point of view.
