arXiv:2108.03604
Abstract
In this paper we introduce a class of color algebras which are called split Lie-Rinehart color algebras as the natural generalization of the one of split LieRinehart algebras. We characterize their inner structures by developing techniques of connections of root systems and weight systems associated to a splitting Cartan subalgebra. We show that such a tight split Lie-Rinehart color algebras $(\LL, A)$ decompose as the orthogonal direct sums $\LL =\oplus_{i\in I}\LL_i$ and where any $\LL_i$ is a non-zero graded ideal of $\LL$ satisfying $[\LL{i_1}, \LL{i_2}, \LL{i_3}]=0$ if be different from each other and any is a non-zero graded ideal of A satisfying if Both decompositions satisfy that for any there exists a unique such that $A_j\LL_i = 0$. Furthermore, any $(\LL_i , A_j )$ is a split LieRinehart color algebra. Also, under certain conditions, it is shown that the above decompositions of $\LL$ and are by means of the family of their, respective, simple ideals.
