Title: CoxeterbiCatalan Combinatorics
Abstract: We pose counting problems related to the various settings for CoxeterCatalan combinatorics (noncrossing, nonnesting, clusters, Cambrian). Each problem involves in some sense a ``doubling'' of a corresponding problem in CoxeterCatalan 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 WbiCatalan number.
This work is joint with my advisor Nathan Reading.
