Winter Meeting 2004  of the 


McGill University - Montréal - CANADA

December 11 - 13, 2004


At the CMS Winter Meeting 2004 in Montreal there will be a special session in Algebraic Combinatorics. Topics include all aspects of algebraic combinatorics and their relations with other parts of mathematics. One particular focus will be on recent work concerning relations among symmetric functions.

    Invited Speakers

Nantel Bergeron York University
Francesco Brenti University of Rome Tor Vergata
Sergey Fomin University of Michigan
Adriano Garsia University of California San Diego
Ian Goulden University of Waterloo
David Jackson University of Waterloo
Mercedes Rosas York University
Mark Skandera Dartmouth College
Richard Stanley Massachusetts Institute of Technology
John Stembridge                      University of Michigan
Stephanie van Willigenburg University of British Columbia
Mike Zabrocki York University

All talks will be 45 minutes. Also of potential interest to combinatorialists at the Winter meeting are the plenary lecture by Persi Diaconis, entitled "A mathematician flips a coin," and the Coxeter-James Prize lecture of Izabella Laba, entitled "Harmonic analysis and combinatorics: Are we there yet?"


All talks will take place in the St. Leonard room at the Hilton Bonaventure Hotel.
