Generalized Derivations in Rings with Involution.

The main purpose of this paper is to study generalized derivations in rings with involution which behave like strong commutativity preserving mappings. In fact, we prove the following result: Let R be a noncommutative prime ring with involution of the second kind such that char . If R admits a generalized derivation associated with a derivation such that for all , then for all or for all . Moreover, a related result is also obtained. [ABSTRACT FROM AUTHOR]
