    "abstract": "We analyze the h-deformations of the Lorentz group and their associated\nspacetimes. We prove that they have a twisted character and give explicitly the\ntwisting matrices. After studying the representations of one of the deformed\nspacetime algebras, we discuss the Klein-Gordon operator. It is found that the\nh-deformed d\u0027Alembertian has plane wave solutions of the same form as the\nstandard ones. We also give explicit expressions for the h-gamma matrices\ndefining the associated Dirac equations.",
