Here we review a new method, recently devised by the author, for obtaining accelerated analytical expressions for these series. The fundamental properties of the new series are studied and an application to a physical example is considered. The relevance of the method to other physical problems is also discussed.8 pages, 2 figures, proceedings of the 8-th International Conference "Path Integrals.
