Abstract	This paper presents a comprehensive structural analysis of derivations acting on Lie ideals in prime rings, investigating their fundamental properties and characterizations. We examine how derivations interact with Lie ideals, focusing on centralizing and commuting conditions that lead to structural constraints in prime rings. The study explores extensions of classical results including Posner's theorems and Herstein's characterizations to more general settings involving generalized derivations and Lie ideals. Our analysis demonstrates that under specific conditions, the existence of certain types of derivations on Lie ideals forces the ring to exhibit commutative behavior or constrains its structure significantly. The results contribute to understanding the interplay between derivations and the Lie structure of prime rings, with implications for both theoretical ring theory and potential applications in algebraic systems. This work synthesizes recent developments in the field while providing new insights into the structural properties of prime rings under derivation conditions.
