Generalized Catalan numbers

Abstract

A finitization of the Catalan numbers Cn C_n can be defined as Euler characteristics of an algebraic structure. We conjecture the existence of a q q -deformed version of such structure, and provide evidence for the first two non-trivial cases. This q q -deformed version will likely categorify series arise from identities of the Roger-Ramanujan type.
