About the Software

The atlas software is written and maintained by Marc van Leeuwen, based on the original code base written by Fokko du Cloux. To install the software, see Download and Install.

The program atlas is designed for interactive exploration of real reductive Lie groups and their representations. It includes the axis programming language, which calls the underlying C++ libraries. The axis language offers standard programming tools (loops, variables, scripts, and so on) with which the user can manipulate the mathematical objects.

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).
