Keywords:
Harmonic polylogarithms, Feynman integrals, General purpose, Function.
Programming language used: Fortran
Computer:
Pentium III/600 MHz PC .
Nature of physical 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.
Method of solution:
For small values of the argument: series representation; other values of
the argument: transformation formulae.
Restrictions:
Limited up to HPL of weight 4, the algorithms used here can be extended
to higher weights without modification.
Typical running time:
On average 0.3 ms for the evaluation of all harmonic polylogarithms up
to weight 4 on a Pentium III/600 MHz Linux PC.
