Electrodynamics as an SU(3) Theory, Majorana Equations


This note shows how electrodynamics can be expressed as a theory in an SU(3) representation space, the Majorana equations (GCUFT2, pp. 149 ff.). The basis elements in this case are the Gell-Mann matrices, suggesting that there are several other forms of classical electrodynamics depending on the basis set chosen. So in these notes for paper 136 it has been shown that electrodynamics can be expressed both as an SU(2) and SU(3) theory.
