Macdonald Polynomials

 
Purpose: This page is to make available some of the resources and results associated to the symmetric functions known as Macdonald polynomials (for the most part, type A only). There are some fantastic conjectures and results discovered all the time associated to this field and my main direction of interest is from their combinatorial perspective.  This hardly does them justice since there is a strong interest from a wide range of fields such as algebraic geometry, representation theory, mathematical physics, etc.

What's new?: I placed programs to compute ribbon operators and the ribbon rule in the Maple section. (11/5/01)  There is a graphical explanation of the statistics by Garsia and Haglund for the q,t-Catalan numbers. (9/7/00).
