Abstract :

A well-known result of Bell and Kappe cite{Bell1} states that there exists no non-zero derivation of a prime ring that acts as a homomorphism or as an anti-homomorphism. In opposite sense one may think of the endomorphisms of prime rings that act as derivations or anti-derivations. In the present paper, it is proved that there exists no automorphism of a prime ring that acts as a derivation or an anti-derivation.

Keywords :

Automorphism, Prime ring, Derivation, Generalized polynomial identity.
