Abstract

Let A\mathcal{A} be a prime \ast-algebra. In this paper, we suppose that Φ:AA\Phi:\mathcal{A}\to\mathcal{A} satisfies Φ(AB)=Φ(A)B+AΦ(B)\Phi(A\diamond B)=\Phi(A)\diamond B+A\diamond\Phi(B) where AB=ABBAA\diamond B = A^{*}B - B^{*}A for all A,BAA,B\in\mathcal{A} .We will show that if Φ(αI2)\Phi(\alpha \frac{I}{2}) is self-adjoint for α{1,i}\alpha\in\{1,i\} then Φ\Phi is additive \ast-derivation.
