However it clearly states that the quantum-field equations can be degenerated into the Dirac wave function and Yang-Mills equations in the non-Abelian gauge field.
Thus, the time variable is removed and one obtains a problem of 3N spatial variables for each of the four components of a Dirac wave function. It is shown here how angular momentum algebra can be used for obtaining a dramatic simplification of the problem.
A related aspect of this constraint is the density represented by the Dirac wave function (14).
