It is our seventh year (previous activities can be found at the archive page). The educational component of our program consists in two weekly seminars (see program and brief description). And everything else is about intensive research, often in cooperation with short-time visitors and local people from organizations like Princeton University, Rutgers University, DIMACS or AT&T. This particular year we also expect very extensive interaction with the Special Program on Lie Groups, Representations and Discrete Mathematics held by the School of Mathematics (for more details see Seminars, People).
