Webmaximal element. The main result of §3 is that every Bruhat interval [u, w] in W/V is lexicographically shellable (cf. Definition 3.1). From this combinatorial property we deduce that the simplicial complex of chains in a nonempty open Bruhat interval (u,w) of W/V triangulates a sphere or a ball, and is therefore WebOn the shape of Bruhat intervals By Anders Bjorner and Torsten Ekedahl Abstract Let (W, S) be a crystallographic Coxeter group (this includes all finite and affine Weyl groups), …
