Numerical evaluation of harmonic polylogarithms

Abstract
Harmonic polylogarithms H(a→;x), a generalization of Nielsen's polylogarithms S_(n,p)(x), appear frequently in analytic calculations of radiative corrections in quantum field theory. We present an algorithm for the numerical evaluation of harmonic polylogarithms of arbitrary real argument. This algorithm is implemented into a FORTRAN subroutine hplog to compute harmonic polylogarithms up to weight 4.

Title of program: hplog version 1.0
Catalogue Id: ADPG_v1_0

Nature of problem
Numerical evaluation of the harmonic polylogarithms up to weight 4 for arbitrary real argument. These functions are emerging in Feynman graph integrals involving more than one mass scale.
