Let $G$ be a twisted reductive group over an algebraically closed field, with Borel subgroup $B$. Let $W$ be its corresponding Weyl group, let $w\in W$, and let $s_i$ be a simple r…

Let $W$ be the Weyl group of a maximal torus contained in a Borel subgroup $B$ of a twisted reductive group over an algebraically closed field. Let $w$ be a minimal-length element…
