Symbolic Expansion of Transcendental Functions
S. Weinzierl ,
Higher transcendental function occur frequently in the
calculation of Feynman integrals in quantum field theory.
Their expansion in a small parameter is a non-trivial task.
We report on a computer program which allows the systematic
expansion of certain classes of functions.
The algorithms are based on the Hopf algebra of nested sums.
The program is written in C++ and uses the
