Abstract
The possible infrared behavior of the gluon propagator is studied anal ytically, using the Schwinger-Dyson equations, in both the axial and t he Landau gauge. The possibility of a gluon propagator less singular t han 1/k(2) when k(2) --> 0 is investigated and found to be inconsisten t, despite claims to the contrary, whereas an infrared enhanced one is consistent. The implications for confinement are discussed.
