TWISTED H-SPACETIMES AND INVARIANT EQUATIONS

We analyze the h-deformations of the Lorentz group and their associate d spacetimes. We prove that they have a twisted character and give exp licitly the twisting matrices. After studying the representations of o ne of the deformed spacetime algebras, we discuss the Klein-Gordon ope rator. It is found that the h-deformed d'Alembertian has plane wave so lutions of the same form as the standard ones. We also give explicit e xpressions for the h-gamma matrices defining the associated Dirac equa tions.
