Extended Poincare parasuperalgebra with central charges and invariant wave equations

We describe irreducible representations of the extended Poincare parasuperalgebra (PPSA) which includes an arbitrary number N of parasupercharges, n (n less than or equal to {N/2}) central charges and an internal symmetry group. We also discuss wave equations which are invariant with respect to the PPSA and propose a parasupersymmetric generalization of the Wess-Zumino model for arbitrary p and N.
