HypExp, a Mathematica package for expanding hypergeometric functions around integer-valued parameters

Abstract

We present the Mathematica package HypExp which allows to expand hypergeometric functions JFJ1_JF_{J-1} around integer parameters to arbitrary order. At this, we apply two methods, the first one being based on an integral representation, the second one on the nested sums approach. The expansion works for both symbolic argument zz and unit argument. We also implemented new classes of integrals that appear in the first method and that are, in part, yet unknown to Mathematica.
