Permutahedra and Associahedra: Generalized associahedra from the geometry of finite reflection groups (1112.3255v1)
Published 14 Dec 2011 in math.CO and math.GR
Abstract: This is a chapter in an upcoming Tamari Festscrift. Permutahedra are a class of convex polytopes arising naturally from the study of finite reflection groups, while generalized associahedra are a class of polytopes indexed by finite reflection groups. We present the intimate links those two classes of polytopes share.
