A note on representations of Lie-Yamaguti algebras induced by left Leibniz algebras

Abstract

It is well-known that each left Leibniz algebra has a natural structure of a Lie-Yamaguti algebra. In this paper it is shown that every left representation of a left Leibniz algebra $(\mathfrak{g}, \cdot)$ induces naturally a representation of the Lie-Yamaguti algebra $(\mathfrak{g}, [,], [\![ , , ]\!])$ that is associated with $(\mathfrak{g}, \cdot)$. Moreover, it is proved that equivalent representations of $(\mathfrak{g}, \cdot)$ give equivalent representations of $(\mathfrak{g}, [,], [\![ , , ]\!])$.
