Abstract :
Let be a finite von Neumann algebra with no central summands of type I1. Assume that δ : M → Mis a nonlinear map satisfying δ([[A, B],C]) = [[δ(A), B],C] + [[A, δ(B)],C]+[[A, B], δ(C)] for any A, B,C ∈With ABC = 0. Then, we prove that there exists an additive derivation d :M→M, such that δ(A) = d(A)+τ(A) for any A ∈M, where τ :M→ ZM is a nonlinear map, such that τ([[A, B],C]) = 0 for any A, B,C ∈Mwith ABC = 0.
