  The propagator for gluons in a space-time dependent field is derived. This is
accomplished by solving the equation of motion for the gluonic Green's
functions. Subsequently a relationship between the quark and the gluon
propagator is presented. With its help characteristics of the bosonic
propagator can be obtained from those of the fermionic and vice versa. Finally,
this relation is discussed for the special case of ultrarelativistic collisions
in the semiclassical limit.
