Abstract
The two-loop three-gluon vertex is calculated in an arbitrary covarian t gauge in the limit, when one of the external; momenta vanishes. The differential Ward-Slavnov-Taylor (WST) identity related to this limit is discussed, and the relevant results for the ghost-gluon vertex and two-point functions are obtained. Together with the differential WST i dentity, they provide another independent way for calculating the thre e-gluon vertex. The renormalization of the results obtained is also pr esented.
