Dirac wave function

Dirac wave function

[di′rak ′wāv ‚fəŋk·shən]
(quantum mechanics)
A function appropriate for describing a spin ½ particle and antiparticle; it is a column matrix with four entries, each of which is a function of the space and time coordinates; the four-components form two first-rank Lorentz spinors.

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).
