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.

A related aspect of this constraint is the density represented by the Dirac wave function (14).
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.
