    "abstract": "A relativistic quantum mechanics is formulated in which all of the\ninteractions are in the four-momentum operator and Lorentz transformations are\nkinematic. Interactions are introduced through vertices, which are bilinear in\nfermion and antifermion creation and annihilation operators, and linear in\nboson creation and annihilation operators. The fermion-antifermion operators\ngenerate a unitary Lie algebra, whose representations are fixed by a first\norder Casimir operator (corresponding to baryon number or charge). Eigenvectors\nand eigenvalues of the four-momentum operator are analyzed and exact solutions\nin the strong coupling limit are sketched. A simple model shows how the fine\nstructure constant might be determined for the QED vertex.",
