The Dirac Equation is a Special Case of the Maxwell-Cassano Equations

submitted by: cloudmichael
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...
