A Note on the Majorana-Oppenheimer Quantum Electrodynamics
  A group theoretical description of the Majorana-Oppenheimer quantum electrodynamics is considered. Different spinor realizations of the Maxwell and Dirac fields are discussed. A representation of the Majorana-Oppenheimer wave equations in terms of the Gel'fand-Yaglom formalism is given.
