Workshop on Unitary Representations of Real Reductive Groups
We recommend all attendees download and install the atlas software (available for linux, Mac and Windows).
Then go to Getting Started (on the documentation web site) to start learning about the software.
A basic reference for the software is Algorithms for Representation Theory of Real Groups by Jeffrey Adams and Fokko du Cloux, J. Inst. Math. Jussieu 8 (2009), 209-259.
The complete details are in Unitary Representations of Real Reductive Groups by Jeffrey Adams, Peter Trapa, Marc van Leeuwen, and David A. Vogan, Jr.
