Cohomology Characterizations of Diagonal Non-Abelian Extensions of Regular Hom-Lie Algebras
In this paper, first we show that under the assumption of the center of h being zero, diagonal non-abelian extensions of a regular Hom-Lie algebra g by a regular Hom-Lie algebra h are in one-to-one correspondence with Hom-Lie algebra morphisms from g to Out ( h ) . The...
