Abstract
The gauge technique generates vertex functions which automatically satisfy Ward identities and which are good approximations to the true vertices for small momenta. We show how to construct such vertex functions for very general situations, including spontaneously broken non-Abelian gauge symmetries and finite-temperature gauge theory. Potential applications are outlined.
