Cup product, Frölicher-Nijenhuis bracket and the derived bracket associated to Hom-Lie algebras
In this paper, we introduce some new graded Lie algebras associated with a
Hom-Lie algebra. At first, we define the cup product bracket and its
application to the deformation theory of Hom-Lie algebra morphisms. We observe
an action of the well-known Hom-analogue of the Nijenhuis-Richardson graded Lie
algebra on the cup product graded Lie algebra. Using the corresponding
semidirect product, we define the Fr\"{o}licher-Nijenhuis bracket and study its
application to Nijenhuis operators. We show that the Nijenhuis-Richardson
graded Lie algebra and the Fr\"{o}licher-Nijenhuis algebra constitute a matched
pair of graded Lie algebras. Finally, we define another graded Lie bracket,
called the derived bracket that is useful to study Rota-Baxter operators on
Hom-Lie algebras.
