Abstract This paper investigates the structural behavior of generalized derivations defined on unital prime Banach algebras whose centers are nontrivial. Generalized derivations, which extend the classical notion of derivations by incorporating an additive mapping alongside a standard derivation, have gained significant attention in functional analysis and ring theory due to their rich algebraic structure and implications for commutativity. In the setting of unital prime Banach algebras, the existence of a nontrivial center introduces additional constraints that profoundly influence the behavior of such mappings. We establish several structural properties of generalized derivations under various functional identities and polynomial constraints. In particular, we prove that if a generalized derivation F associated with a derivation d satisfies certain central-valued conditions on a prime Banach algebra A, then both F and d must exhibit specific commutativity-forcing behaviors. A series of commutativity theorems are derived, demonstrating that the algebra A is necessarily commutative under prescribed conditions involving the action of F on the center or on Lie ideals of A. Our results generalize and extend several known theorems in the literature on prime rings and Banach algebras. Applications to automatic continuity and the Singer–Wermer conjecture are also discussed.
