Hom-algebras and homology. (English) Zbl 1252.17002

Summary: Classes of \(G \)-Hom-associative algebras are constructed as deformations of \(G \)-associative algebras along algebra endomorphisms. As special cases, we obtain Hom-associative and Hom-Lie algebras as deformations of associative and Lie algebras, respectively, along algebra endomorphisms. Chevalley-Eilenberg type homology for Hom-Lie algebras are also constructed.
