Well-poised generation of Ap\'ery-like recursions
Abstract
The idea to use classical hypergeometric series and, in particular, well-poised hypergeometric series in diophantine problems of the values of the polylogarithms has led to several novelties in number theory and neighbouring areas of mathematics. Here we present a systematic approach to derive second-order polynomial recursions for approximations to some values of the Lerch zeta function, depending on the fixed (but not necessarily real) parameter satisfying the condition . Substituting into the resulting recurrence equations produces the famous recursions for rational approximations to , due to Ap\'ery, as well as the known recursion for rational approximations to . Multiple integral representations for solutions of the constructed recurrences are also given.
