AMS special session on rings, algebras and varieties in combinatorics:


Patricia Hersh, Indiana University and North Carolina State University, phersh at
Cristian Lenart, SUNY Albany, lenart at
Nathan Reading, North Carolina State University, nreadin at

Location: April 4-5, 2009 at North Carolina State University in Raleigh, North Carolina. Raleigh-Durham International Airport (RDU) is 20 minutes drive from NCSU.

Hotels: The AMS hasn't yet given hotel recommendations, but two hotels which are within easy walking distance of the math department at NCSU are the Holiday Inn Brownstone Hotel (800-331-7919) and the Velvet Cloak Inn (888-828-0335 toll free). Another very well-located option, which is a little fancier, is the Cameron Park Inn Bed and Breakfast (888-257-2171).

Abstract submission deadline: February 10, 2009, to be submitted electronically at the AMS abstract submission web site

Focus themes of the session: Macdonald polynomials, cluster algebras and totally nonnegative spaces, Schubert varieties, Hilbert series and face numbers
