  An algebraic description of basic physical fields (neutrino field,
electron-positron field and electromagnetic field) is studied. It is sown that
the electromagnetic field can be described within a quotient representation of
the proper orthochronous Lorentz group. The relation of such a description with
Majorana-Oppenheimer quantum electrodynamics and de Broglie-Jordan neutrino
theory of light is discussed.
