Manuscript Title: WBase: a C package to reduce tensor products of Lie algebra representations.
Authors: A. Candiello
Program title: WBASE
Catalogue identifier: ACTK_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 81(1994)248
Programming language: C.
Computer: VAX 4000/90.
Operating system: VMS 5.5-2, ULTRIX V4.3A.
Word size: 32
Keywords: General purpose, Lie algebras, Tensor products, Irreducible, Representations.
Classification: 4.2.

Nature of problem:
Irreducible representation manipulations are needed in a wide number of physical arguments, such as high energy particle physics, supergravity theories, grand unification models.

Solution method:
The Dynkin technique for manipulating Lie algebra irreps is used. A sophisticated dynamic allocation scheme allows our program to use memory only when really needed.

Restrictions:
The limit on the application of our program is related to the dimension of the irreducible representations needed when computing tensor products; this limit is dependent on the hardware, as dynamic allocation does not set software bounds to the size of data.

Running time:
2.41 s for the test run
