Description

Abstract In this article, we describe a new algorithm for the expansion of hypergeometric functions about half-integer parameters. The implementation of this algorithm for certain classes of hypergeometric functions in the already existing Mathematica package HypExp is described. Examples of applications in Feynman diagrams with up to four loops are given. Title of program: HypExp 2 Catalogue Id: ADXF_v2_0 Nature of problem Expansion of hypergeometric functions about parameters that are integer and/or half-integer valued.
