Borel resummation
WebHowever, in contrast to singularly perturbed problems, Borel resummation and \'Ecalle's resurgence theory have mainly focused on non-parametric asymptotic expansions (i.e. differential equations ... WebThere is a well-known resummation procedure due to Borel that allows to nd a suitable analytic continuation of an asymptotic series: Basically it consists in taking the Laplace trans- form of the function obtained by resumming the original series after dividing their terms by a factorially growing coecient.In special cases, such as the anharmonic …

It is particularly useful for summing divergent asymptotic series, and in some sense gives the best possible sum for such series. There are several variations of this method that are also called … See more There are (at least) three slightly different methods called Borel summation. They differ in which series they can sum, but are consistent, meaning that if two of the methods sum the same series they give the same answer.
