Abstract

Let A\mathcal {A} be a unital \ast-algebra. For A,BAA, B\in\mathcal{A}, define by [A,B]=ABBA[A, B]_{*}=AB-BA^{\ast} and AB=AB+BAA\bullet B=AB+BA^{\ast} the new products of AA and BB. In this paper, under some mild conditions on A\mathcal {A}, it is shown that a map Φ:AA\Phi:\mathcal {A}\rightarrow \mathcal {A} satisfies Φ([AB,C])=[Φ(A)B,C]+[AΦ(B),C]+[AB,Φ(C)]\Phi([A\bullet B, C]_{*})=[\Phi(A)\bullet B, C]_{*}+[A\bullet \Phi(B), C]_{*}+[A\bullet B, \Phi(C)]_{*} for all A,B,CAA, B,C\in\mathcal {A} if and only if Φ\Phi is an additive *-derivation. In particular, we apply the above result to prime \ast-algebras, von Neumann algebras with no central summands of type I1I_1, factor von Neumann algebras and standard operator algebras.
