Cohomology and Crossed Module Extensions of Hom-Leibniz-Rinehart Algebras

In this paper, we introduce the concept of crossed module for Hom-Leibniz-Rinehart algebras. We then study the cohomology and extension theory of Hom-Leibniz-Rinehart algebras. It is proved that there is a one-to-one correspondence between equivalence classes of abelian extensions of Hom-Leibniz-Rinehart algebras and the elements of second cohomology group. Furthermore, we prove that there is a natural map from α-crossed module extensions of Hom-Leibniz-Rinehart algebras to the third cohomology group of Hom-Leibniz-Rinehart algebras.
