Abstract

Let RR be a ring and Z(R)Z(R) be the center of R.R. The aim of this paper is to define the notions of centrally extended Jordan derivations and centrally extended Jordan \ast-derivations, and to prove some results involving these mappings. Precisely, we prove that if a 22-torsion free noncommutative prime ring RR admits a centrally extended Jordan derivation (resp. centrally extended Jordan \ast-derivation) δ:RR\delta:R\to R such that [δ(x),x]Z(R)  (resp.  [δ(x),x]Z(R)) for all xR, [\delta(x),x]\in Z(R)~~(resp.~~[\delta(x),x^{\ast}]\in Z(R))\text{~for~all~}x\in R, where '\ast' is an involution on R,R, then RR is an order in a central simple algebra of dimension at most 4 over its center.
