On some enumerative aspects of generalized associahedra

We prove a conjecture of F. Chapoton relating certain enumerative invariants of (a) the cluster complex associated by S. Fomin and A. Zelevinsky with a finite root system and (b) the lattice of noncrossing partitions associated with the corresponding finite real reflection group. c 2006 Elsevier Ltd. All rights reserved.
