Abstract
We classify extended Poincaré Lie superalgebras and Lie algebras of any signature (p, q), i.e. Lie superalgebras and ℤ2-graded Lie algebras g = g0 + g1, where g0 = s0(V) + V is the (generalized) Poincaré Lie algebra of the pseudo Euclidean vector space V = ℝp, q of signature (p, q) and g1 is a spin 1/2 s0(V)-module extended to a s0-module with kernel V.
As a result of the classification, we obtain, if g1 = S is the spinor module, the numbers L +(n, s) (resp. L −(n, s)) of independent such Lie super algebras (resp. Lie algebras), which are periodic functions of the dimension n=p+q (mod 8) and the signature s=p−q (mod 8) and satisfy: L +(−n, s)=L − (n, s).
