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.
The program 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
suffix .at
(or occasionally .ax
).
This library has
been developed by Marc van Leeuwen, Jeffrey Adams, Annegret Paul, David Vogan
and others.
