Abstract
Applying the principle of analytic extension for generalized functions we derive causal propagators for algebraic non-covariant gauges. The so-generated manifestly causal gluon propagator in the light-cone gaug e is used to evaluate two one-loop Feynman integrals which appear in t he computation of the three-gluon vertex correction. The result is in agreement with that obtained through the usual prescriptions.
