WebBruhat Family History Bruhat Name Meaning Historically, surnames evolved as a way to sort people into groups - by occupation, place of origin, clan affiliation, patronage, parentage, … WebThe Bruhat order is implemented in Sage as a method of Coxeter groups, and so it is available for Weyl groups, classical or affine. If u, v ∈ W then u.bruhat_le (v) returns True if u ≤ v in the Bruhat order. If u ≤ v then the Bruhat interval [ u, v] is defined to be the set of all t such that u ≤ t ≤ v. One might try to implement this as follows:
