About the Software¶
There are two programs installed by the instructions in
Download and Install. The underlying software
library is called
Fokko in honor of its primary architect Fokko du Cloux.
Fokko worked on the software in 2004 and 2005.
Since then Marc van Leeuwen is the primary software developer.
atlas is designed for interactive exploration of real
reductive Lie groups and their representations. It has been developed
by Marc van Leeuwen since 2006. It is built on a programming language
axis, also developed by Marc van Leeuwen. The atlas software
invokes (invisibly to the user!) the libraries of
Fokko to create
mathematical objects; then the
axis language offers standard
programming tools (loops, variables, scripts, and so on) with which
the user can manipulate them.
An important part of
atlas is the
(constantly growing) library of predefined scripts, which can be used
or modified to do interesting mathematical tasks.
These files are found in the
atlas-scripts directory, and have the
.at (or occasionally
This library has
been developed by Marc van Leeuwen, Jeffrey Adams, Annegret Paul, David Vogan
