The Dirac Equation is a Special Case of the Maxwell-Cassano Equations
For vector Phi of D
The Klein-Gordon equation may be written (see reference (4)):
Whenever Phi of D is a 2 to the M-dimensional vector, via a matrix differential operator factorization, it may be written (in the Dirac representation), as shown here:
and, since these matrix operators are commutative:
conformability of the matrices requires thatthese matrices
are all 2×1 matrices; yielding:
For symmetry...
