TOTAL GLUON PROPAGATOR IN LIGHT-CONE GAUGE AND THE TRANSVERSALITY PROBLEM OF THE POLARIZATION OPERATOR IN THE INFRARED REGION .2.

A three-gluon vertex that depends on a gauge vector np and is free of kinematic and spurion (np)(-1) singularities in the physical region is constructed. It is shown that in the case of integer power-law asympt otic behavior of the gluon propagator there is separation of the singu lar contributions of the single- and two-loop diagrams iri the Dyson-S chwinger equation. Necessary conditions for realization of p(-4) asymp totic behavior are obtained, and it is shown that an important role in their fulfillment is played by the parts of the three-gluon vertex th at depend on the gauge vector. A solution of these conditions is found ; when they are fulfilled, they lead to infrared; asymptotic behaviors of the complete Dyson-Schwinger equation and its single-loop approxim ation that are mutually compatible.
