Nonlinear Skew Lie Triple Derivations between Factors

Abstract Let A be a factor. For A, B ∈4, define by [A, B]. = AB- BA* the skew Lie product of A and B. In this article, it is proved that a map φ: A- A satisfies φ([[A, B]., C].) = [[φ(A), B]., C]. + [[A, φ(B)]. C]. + [[A, B]., φ(C)]. for all A, B, C∈ A if and only if φ is an additive *-derivation....
