    "abstract": "The mass operator M is introduced as an independent dynamical variable which\nis taken as the translation generator P_4 of the inhomogenous De Sitter group.\nThe classification of representations of the algebra P(1,4) of this group is\nperformed and the corresponding P(1,4) invariant equations for variable-mass\nparticles are written out. In this way we have succeeded, in particular, in\nuniting the ``external\u0027\u0027 and ``internal\u0027\u0027 (SU_2) symmetries in a non-trivial\nfashion.",
