(Bi)Hom-Leibniz algebras

Abstract

The first aim of this paper is to introduce and study symmetric (Bi)Hom-Leibniz algebras, which are left and right Leibniz algebras. We discuss ${\alpha }^k{\beta }^l$-generalized derivations, ${\alpha }^k{\beta }^l$ -quasi-derivations and ${\alpha }^k{\beta }^l$-quasi-centroid of (Bi)Hom-Leibniz algebras and colour BiHom-Leibniz algebras. The second aim is to define a new type of BiHom-Lie algebras satisfies the following hierarchy \begin{equation*} \displaystyle \{ \text{ BiHom-Lie type $B_1$} \}\supseteq_{β=id} \{ \text{ Hom-Lie} \}\supseteq_{α=id} \{ \text{ Lie} \}. \end{equation*} Moreover, define representations and a cohomology of symmetric BiHom- Leibniz algebras of type $B_1$.
