WebOn the shape of Bruhat intervals ***** EN. English Deutsch Français Español Português Italiano Român Nederlands Latina Dansk Svenska Norsk Magyar Bahasa Indonesia … WebA Bruhat interval polytope Qv,w is toric if and only if every subin-terval [x,y] of [v,w] is realized as a face of Qv,w. The above theorem implies that if Qv,w is toric, then its combinatorial type is determined by the poset structure of [v,w], and hence Qv,w and Qv−1,w−1 are combinatorially equivalent.
