The purpose of the program is to communicate results and ideas rather than to deliver polished presentations. The program also serves to acquaint graduate students in this area with a range of researchers in Lie theory and representation theory.
The Fall 2014 workshop took place at the University of Washington (Seattle), November 15-16, 2014. The local organizer was James Zhang and the emphasis will be on Hopf algebras and actions.
Spring 2014: University of Southern California (USC), May 19-22. The local organizers were Aravind Asok, Robert Guralnick, Aaron Lauda and Susan Montgomery. This
conference was joint with a conference in celebration of the 70th birthday of Eric Friedlander. https://sites.google.com/site/efriedlander70/
