In the present paper we prove that, let R be a prime ring with center Z, L a Lie ideal of R and σ a nontrivial automorphism of R such that (i){ σ(u) } n- (u) 2 m + 1= 0 , (ii){ σ(u) } n- (u) 2 m + 1∈ Z, (iii) { σ(u) } n+ (u) 2 m= 0 forallu∈L and fixed n, m≥ 1. If either char (R) > n+ 1 or char (R) = 0 , then L⊆ Z. © 2016, Springer-Verlag Italia.
