Title:  Coxeter-biCatalan Combinatorics

Abstract:   We pose counting problems related to the various settings for Coxeter-Catalan combinatorics (noncrossing, nonnesting, clusters, Cambrian). Each problem involves in some sense a ``doubling'' of a corresponding problem in Coxeter-Catalan combinatorics. We show that the problems all have the same answer, and we call the common solution to these problems for a given finite Coxeter group W the W-biCatalan number.

This work is joint with my advisor Nathan Reading.
