Enumerative Properties of Generalized Associahedra
Some enumerative aspects of the fans called generalized associahedra,
introduced by S. Fomin and A. Zelevinsky in their theory of cluster
algebras, are considered in relation with a bicomplex and its two
spectral sequences. A precise enumerative relation with the lattices
of generalized noncrossing partitions is conjectured and some evidence
