WebApr 27, 2012 · The existence of a Bruhat decomposition for a number of classical groups was established in 1956 by F. Bruhat, and was proved in the general case by C. Chevalley . A. A. Web4 Bruhat-Tits buildings F. Bruhat and J. Tits have described the analog of the Cartan decomposition for semisimple groups over non-archimedean local fields, in [4], [5], [6] and [7], by introducing new geometric spaces that are nowaday called Bruhat-Tits buildings and that extend the space of p-adic norms studied by Goldman and Iwahori in [10]. 4

For w ∈ W the closure Xw = BwB/B itself has the cellular decomposition {BuB/B u ∈ W, u ≤ w}, and so its poset of cells QXw is the interval [e,w] in Bruhat order on W below the ... WebBRUHAT TYPE. Let us call a nontrivial poset P with 0 a poset of Bruhat type if every lower interval [0, x], x E P, is isomorphic to an interval in the Bruhat ordering of a Coxeter group. Such intervals are spherical [4, Theorem 5.4], so these posets are CW posets. Clearly, every nontrivial interval or order ideal in the Bruhat ordering of a Coxeter fha form 92541 builder\\u0027s certification
