We apply the theory of generalized polynomial identities with automorphism and skew derivations to obtain the following result: Let R be a prime ring and I a nonzero ideal of R. Suppose that .(𝛿 , 𝜑) is a skew derivation of R such that 𝛿([ x,y] =[x,y]n• for all x , y ∈ I , then R is commutative.en-USSkew DerivationsPrime RingsAutomorphismThesis
