Ward-Schwinger-Dyson equations allow to obtain relations in quantum field theory directly on renormalised green functions. The solutions of their truncation at any order satisfy renormalisation group equations and presumably any symmetry associated to a gauge symmetry.

We indicate how they can be used to prove results on the resurgent nature of the various functions used to study quantum field theory, anomalous dimensions or propagators.
