Programming language: Reduce. | ||

Computer: IBM 360/370. | ||

Operating system: OS, VM. | ||

RAM: 400K words | ||

Word size: 32 | ||

Keywords: General purpose, Diagramatic expansions, Computer algebra, Gauge field theory, Feynman diagrams, Perturbation theory, Lie groups, Symbolic calculations. | ||

Classification: 4.4, 5. | ||

Nature of problem:Computations of Feynman diagrams in non-Abelian gauge field theories involves the group-theoretic weight computation. The present program implements the Cvitanovic algorithm of computation of the group- theoretic weight for SU(n) and SO(n). | ||

Restrictions:The available computer memory is the severest restriction. | ||

Running time:Strongly depends on a concrete form of the diagram. The running time of test examples is 4 to 40 sec. on the computer EC-1040. |
