## Rational Catalan combinatorics

### Edited by org.aimpl.user: armstrong@math.miami.edu and org.aimpl.user:will3089@umn.edu

D. Armstrong, S. Griffeth, V. Reiner, and M. Vazirani arranged for three groups of mathematicians to spend the week of December 16th at the American Institute of Mathematics for a workshop on Rational Catalan Combinatorics. The three areas of study these mathematicians represented were:
1. Catalan Combinatorics and Reflection Groups;
2. Symmetric Functions, Macdonald Polynomials, and Diagonal Harmonics; and
3. Rational Cherednik algebras.
What follows is a summary of the two moderated problem sessions from the workshop. The brave moderators who led these sessions were N. Reading and E. Niece.
