We introduce the following notion. Let N 0 be the set of all nonnegative integers and let = ( ) ∈N 0 be a family of additive mappings of a * -ring R such that 0 = ; D is called a Jordan higher * -derivation (resp., a Jordan higher) for all , ∈ and each ∈ N 0 . It is shown that the notions of Jordan higher * -derivations and Jordan triple higher * -derivations on a 6-torsion free semiprime * -ring are coincident.
We investigate the additivity and multiplicativity of centrally extended higher derivations and show that every centrally extended higher derivation of a semiprime ring with no nonzero central ideals is a higher derivation. Moreover, we study preservation of the center of the ring by a centrally extended higher derivation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
