Users' guide to the Atlas software package

Last updated: October 8, 2005

The aim of this package is to provide tools for the exploration by computer of the combinatorial and algorithmic aspects of the representation theory of reductive Lie groups (for the time being, real reductive Lie groups; see here for a precise description of the class of groups under consideration.) The current (and very preliminary) version is 0.2.2 (download)

For the time being, the package is provided with the command line interface that is used during its development. The intention is to ultimately release it in the form of a set of libraries, with hopefully a number of interfaces to high-level systems such as Maple, Mathematica or GAP.

The main capabilities of the program are the following :

The program is distributed under the copyleft license of the Free Software Foundation; therefore it is not in the public domain, but may be freely copied, distributed, modified, and incorporated into other software, provided only that the modified versions be clearly identified as such, and that programs incorporating all or part of this code be in turn distributed under the copyleft license.
