| Manuscript Title: XSummer: Transcendental Functions and Symbolic Summation in FORM | ||
| Authors: S. Moch, P. Uwer | ||
| Program title: XSummer | ||
| Catalogue identifier: ADXQ_v1_0 Distribution format: tar.gz | ||
| Journal reference: Comput. Phys. Commun. 174(2006)759 | ||
| Programming language: Form (http://www.nikhef.nl/~form/). | ||
| Computer: all. | ||
| Operating system: all. | ||
| RAM: Depending on the complexity of the problem, recommended at least 64 MB RAM. | ||
| Keywords: Symbolic summation, Multiple polylogarithms, Transcendental functions. | ||
| PACS: 02.70.Wz, 03.65.Fd. | ||

Nature of problem: Systematic expansion of higher transcendental functions in a small parameter. The expansions arise in the calculation of loop integrals in perturbative quantum field theory. | ||
Solution method: Algebraic manipulations of nested sums. | ||
Restrictions: Usually limited only by the available disk space. | ||
Running time: Dependent on the complexity of the problem. |
