Research output: Contribution to journalArticlepeer-review


We conjecture a formula for the rational q, t-Catalan polynomial Cr/s that is symmetric in q and t by definition. The conjecture posits that Cr/s can be written in terms of symmetric monomial strings indexed by maximal Dyck paths. We show that for any finite d , giving a combinatorial proof of our conjecture on the infinite set of functions {Cr/sd:r≡1mods,d≤d∗} is equivalent to a finite counting problem.
