We give some constructions of Hom-Poisson color algebras first from a Hom-associative color algebra which twisting map is an averaging operator, then from a given Hom-Poisson color algebra and an averaging operator and finally from a Hom-post-Poisson color algebra. Then we show that any Hom-pre-Poisson color algebra leads to a Hom-Poisson color algebra. Conversly, we prove that any Hom-Poisson color algebra turn to a Hom-pre-Poisson color algebra via Rota-Baxter operator.Koszul dualization. Some examples and related structures are given. Among other results, the authors proved in [5] that tridendriform and Rota-Baxter Lie algebras lead to the structures of post-Lie algebras. Post-Poisson algebras [6] are algebraic structures containing post-Lie algebras [4], [9] and pre-Poisson algebras [13] which contain pre-Lie algebras (or left-symmetric algebras) and Zinbiel algebras, both structures being connected by some compatibility conditions.Classical (or ordinary) algebras were extended to generalized (or color or graded) algebras, among which one can cite : Simple Jordan color algebras arising from associative graded algebras [11], Representations and cocycle twists of color Lie algebras [16], On the classification of 3-dimensional coloured Lie algebras [15]. These structures are well-known to physicists and to mathematicans studying differential geometry and homotopy theory. They were extended to the Hom-setting by studying Hom-Lie superalgebras, Rota-Baxter operator on pre-Lie superalgebras and beyound [8] and Hom-Lie color algebras [12]. Color Hom-Poisson algebras were introduced in [10] as generalization of Hom-Poisson algebras [1].The aim of this paper is to introduce and study the relationship among commutative Hom-tridendriform color algebras and Hom-post-Poisson color algebras. The paper is organized as follows. In section 2, we recall definition of Hom-Poisson color algebras and define averaging operator on Hom-associative and Hom-Lie color algebras. We introduce Hom-post-Lie color algebras, and give some procedures of construction of Hom-post-Lie color algebras form either a given one or from Hom-Lie Rota-Baxter color algebras. The section 3 is devoted to the main results of this paper i.e. some constructions of Hom-Poisson color algebras from other algebraic structures.Throughout this paper, all graded vector spaces are assumed to be over a field K of characteristic different from 2.
PreliminariesWe give basic notions and give some of their properties.Let G be an abelian group. A vector space V is said to be a G-graded if, there exists a family (V a ) a∈G of vector subspaces of V such thatAn element x ∈ V is said to be homogeneous of degree a ∈ G if x ∈ V a . We denote H(V ) the set of all homogeneous elements in V .Let V = ⊕ a∈G V a and V = ⊕ a∈G V a be two G-graded vector spaces. A linear mapping f : V → V is said to be homogeneous of degree b if f (V a ) ⊆ V a+b , ∀a ∈ G.
