The construction of 3-Bihom-Lie algebras

Abstract

The purpose of this paper is to study the construction of $3$-Bihom-Lie algebras. We give some ways of constructing $3$-Bihom-Lie algebras from $3$-Bihom-Lie algebras and $3$-totally Bihom-associative algebras. Furthermore, we introduce $T_\theta$-extensions and $T_\theta^*$-extensions of $3$-Bihom-Lie algebras and prove the necessary and sufficient conditions for a $2n$-dimensional quadratic $3$-Bihom-Lie algebra to be isomorphic to a $T_\theta^*$-extension.
