Characterizations of Jordan derivations on rings: additive maps Jordan derivable at an idempotent

摘要：

Let A be a unital ring containing a nontrivial idempotent P and φbe an additive map from A into itself. We say an element Z ∈A is a Jordan derivable point of A if φ(A)B+Aφ(B)+ φ(B)A+Bφ(A)=φ(Z) for every A,B∈A with AB+BA=Z. In this paper, we characterize additive maps Jordan derivable at idempotent.
