Abstract

FF-Lie algebras are natural generalisations of Lie algebras (F=1) and Lie superalgebras (F=2). When F>2F>2 not many finite-dimensional examples are known. In this paper we construct finite-dimensional FF-Lie algebras F>2F>2 by an inductive process starting from Lie algebras and Lie superalgebras. Matrix realisations of FF-Lie algebras constructed in this way from su(n),sp(2n)\mathfrak{su}(n), \mathfrak{sp}(2n) so(n)\mathfrak{so}(n) and sl(nm)\mathfrak{sl}(n|m), osp(2m)\mathfrak{osp}(2|m) are given. We obtain non-trivial extensions of the Poincar\'e algebra by In\"on\"u-Wigner contraction of certain FF-Lie algebras with F>2F>2.
