Abstract

We show how various constructions of Z\mathbb{Z}-graded Lie superalgebras are related to each other. These Lie superalgebras have a Lie algebra g\mathfrak{g} as the subalgebra at degree 0, an odd g\mathfrak{g}-module V as the subspace at degree 1, and an embedding tensor as an element at degree -1. This is a linear map from V to g\mathfrak{g} satisfying a quadratic constraint, which equips V with the structure of a Leibniz algebra.
