Does the new version supersede the previous version?: No. It is an extension to the previous program, which performs reductions of hypergeometric functions pFp, F1, F2, F3 and F4
Nature of problem:
Reduction of hypergeometric functions FD and FS to the set of basis functions.
Reasons for new version:
New algorithms for the reduction of multivariable Lauricella functions, Horn functions, (hypergeometric functions FD and FS)
Summary of revisions:
HYPERDIRE is a project devoted to the creation of a set of Mathematica based programs for the differential reduction of hypergeometric functions. The current version includes two parts: the first one, FdFunction, for manipulations with Appell hypergeometric functions FD of r variables; and the second one, FsFunction, for manipulations with Lauricella-Saran hypergeometric functions FS of three variables. Both functions are related with one-loop Feynman diagrams.
Depends on the complexity of problem.
