Abstract
It is shown that the effective gluon propagator in the global color symmetr y model can be calculated in the instanton dilute liquid approximation. The calculated effective gluon propagator is consistent with the general comma nd on the qualitative features of the gluon propagator, i.e., (i) the gluon propagator is significantly enhanced at small space-like k(2), and (ii) fo r k(2) > 1.5 GeV2 the perturbative results are quantitatively reliable.
