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 is given.Comment: 15 page
