In Proposition 4.9 and Propo-sition 4.10, we describe explicitly the covering relations of ˚ I for a coweight when is mildly regular. In Section 4.3, we show that for any two positive roots ... WebFor a given irreducible root system, we introduce a partition of (coweight) lattice points inside the dilated fundamental parallelepiped into those of partially closed simplices. This partition can be considered as a generalization and a lattice points interpretation of the classical formula of Worpitzky. This partition, and the generalized Eulerian polynomial, …
