Abstract:

In this article, it is shown that a map ξ : ???? → ???? (not necessarily linear) satisfies ξ((A ∘ B) ∙ C) = (ξ(A) ∘ B) ∙ C + (A ∘ ξ(B)) ∙ C + (A ∘ B) ∙ ξ(C) holds for all A,B,C ∈ ???? if and only if ξ is an additive ∗-derivation where ???? a unital ∗-algebra over the complex fields ℂ. As applications, we apply our main result to some special classes of unital ∗-algebras such as prime ∗-algebras, standard operator algebras, factor von Neumann algebras and von Neumann algebras with no central summands of type I1.



Keywords:

Additive ∗-derivation, mixed bi-skew Jordan triple derivation, ∗-algebras, Von Neumann algebra.
