Weak-coupling, strong-coupling and large-order parametrization of the hypergeometric-Meijer approximants

Without Borel or Padé techniques, we show that for a divergent series with n! large-order growth factor, the set of hypergeometric series pFp-2 represents suitable approximants. The divergent pFp-2 series are then resummed via their representation in terms of the Meijer-G function. The choice of pFp...
