  • Hussien Jaber Thahab

General Background Γ-rings represent an important generalization of classical ring theory and provide a broader framework for studying algebraic mappings and structural properties of algebraic systems. Specific Background In derivation theory, several generalizations such as Jordan derivations, higher derivations, and reverse derivations have been investigated to understand additive mappings in rings and Γ-rings. Knowledge Gap Despite these developments, the structure and properties of higher reverse α-derivations in 2-torsion free semiprime Γ-rings have received limited theoretical attention. Aims This study introduces the concept of higher reverse α-derivations on semiprime Γ-rings and investigates related notions including Jordan higher reverse α-derivations and Jordan triple higher reverse α-derivations. Results The paper formulates definitions for these mappings and establishes several algebraic identities and structural relations that describe their behavior in the setting of semiprime Γ-rings. A series of lemmas and algebraic derivations demonstrate how these mappings interact with the Γ-ring structure and generalize classical results from derivation theory. Novelty The work extends the framework of reverse derivations by introducing higher reverse α-derivations and analyzing their structural properties in 2-torsion free semiprime Γ-rings. Implications These results contribute to the theoretical development of derivation theory in generalized algebraic systems and provide a foundation for further investigations of generalized derivations, higher mappings, and related operator structures within Γ-rings and other algebraic frameworks. Keywords: Semiprime Gamma Ring, Higher Reverse Alpha Derivation, Jordan Higher Reverse Derivation, Derivation Theory, Algebraic Structures Key Findings Highlights Structural identities describing higher reverse α-derivations in semiprime Γ-rings were formulated. Algebraic relations for Jordan higher reverse and Jordan triple higher reverse mappings were established. The study extends classical derivation theory to generalized Γ-ring structures.
