# Generalized Kostka Polynomials

July 18 to July 22, 2005

at the

American Institute of Mathematics, Palo Alto, California

organized by

Anne Schilling and Monica Vazirani

## Original Announcement

This workshop concerns Kostka polynomials and their connections to various areas of mathematics. Kostka polynomials and their generalizations have arisen in numerous ways such as in the context of symmetric functions, combinatorics, representation theory, quantum groups and crystal bases, statistical mechanics, algebraic geometry, and Kazhdan-Lusztig theory. The goal of this workshop is to bring together mathematicians who have studied Kostka polynomials from different points of views, state the various connections and open conjectures, and work towards their proofs.
