Non-abelian extensions of Hom-Jacobi-Jordan algebras

Abstract

This paper develops a cohomology theory for Hom-Jacobi-Jordan algebras using and applies it to classify non-abelian extensions. The main result establishes that equivalence classes of split extensions of a Hom-Jacobi-Jordan algebra $J$ by $V$ are in bijection with the second cohomology group $H^2(J,V)$, generalizing classical results from Lie and Leibniz algebra theory. We characterize extensions explicitly through 2-cocycles $(\rho ,\theta )$ satisfying compatibility conditions, and provide complete classifications of low-dimensional cases.
