Abstract
The expression connecting the gluon propagator in noncovariant gauge directly with the gluon propagator in special covariant gauge is derived. All renormalization theorems, which were proved for covariant gauges, apply also in the case of noncovariant gauge conditions. Spectral functions of the gluon propagator in noncovariant and covariant gauges are connected. The violation of translation invariance is contained in spectral functions for axial type gauges.
