Asymptotic power series of field correlators
Irinel Caprini, Jan Fischer, Ivo Vrkoč
We address the problem of ambiguity of a function determined by an asymptotic perturbation expansion. Using a modified form of the Watson lemma recently proved elsewhere, we discus…

On the ambiguity of functions represented by divergent power series
Irinel Caprini, Jan Fischer, Ivo Vrkoč
Assuming the asymptotic character of divergent perturbation series, we address the problem of ambiguity of a function determined by an asymptotic power expansion. We consider funct…
