BiHom-Lie superalgebra structures (1610.02290v1)

Abstract: The aim of this paper is to introduce the notion of BiHom-Lie superalgebras. This class of algebras is a generalization of both BiHom-Lie algebras and Hom-Lie superalgebras. In this article, we first present two ways to construct BiHom-Lie superalgebras from BiHom-associative superalgebras and Hom-Lie superalgebras by Yau's twist principle. Also, we explore some general classes of BiHom-Lie admissible superalgebras and describe all these classes via $G$-BiHom-associative superalgebras, where $G$ is a subgroup of the symmetric group $S_{3}$. Finally, we discuss the concept of $\beta^{k}$-derivation of BiHom-Lie superalgebras and prove that the set of all $\beta^{k}$-derivation has a natural BiHom-Lie superalgebra structure.
