Non-Perturbative Asymptotic Improvement of Perturbation Theory and Mellin-Barnes Representation
Using a method mixing Mellin-Barnes representation and Borel resummation we show how to obtain hyperasymptotic expansions from the (divergent) formal power series which follow from the perturbative evaluation of arbitrary ''N-point'' functions for the simple case of zero-dimensio...
