Abstract

The Abelian semigroup expansion is a powerful and simple method to derive new Lie algebras from a given one. Recently it was shown that the SS-expansion of so(3,2)\mathfrak{so}\left( 3,2\right) leads us to the Maxwell algebra M\mathcal{M}. In this paper we extend this result to superalgebras, by proving that different choices of abelian semigroups SS lead to interesting D=4D=4 Maxwell Superalgebras. In particular, the minimal Maxwell superalgebra sMs\mathcal{M} and the NN-extended Maxwell superalgebra sM(N)s\mathcal{M}^{\left( N\right) } recently found by the Maurer Cartan expansion procedure, are derived alternatively as an SS-expansion of osp(4N)\mathfrak{osp}\left( 4|N\right) . Moreover we show that new minimal Maxwell superalgebras type sMm+2s\mathcal{M}_{m+2} and their NN-extended generalization can be obtained using the SS-expansion procedure.
