Connections to Rota-Baxter operators and Yang-Baxter equation are established.
Abstract
Quadri-algebras introduced by Aguiar and Loday are a class of remarkable Loday algebras. In this paper, we introduce a notion of L-quadri-algebra with 4 operations satisfying certain generalized left-symmetry, as a Lie algebraic analogue of quadri-algebra such that the commutator of the sum of the 4 operations is a Lie algebra. Any quadri-algebra is an L-quadri-algebra. Moreover, L-quadri-algebras fit into the framework of the relationships between Loday algebras and their Lie algebraic analogues, extending the well known fact that the commutator of an associative algebra is a Lie algebra. We also give the close relationships between L-quadri-algebras and some interesting structures like Rota-Baxter operators, classical Yang-Baxter equation, some bilinear forms satisfying certain conditions.
