Jordan derivations on certain Banach algebras

Abstract

In this paper, we study the types of Jordan derivations of a Banach algebra AA with a right identity ee. We show that if eAeA is commutative and semisimple, then every Jordan derivation of A A is a derivation. In this case, Jordan derivations map AA into the radical of AA. We also prove that every Jordan triple left (right) derivation of A A is a Jordan left (right) derivation. Finally, we investigate the range of Jordan left derivations and establish that every Jordan left derivation of A A maps A A into eAeA.
