Torus orbit closures in flag varieties and retractions on Weyl groups
A finite Coxeter group W has a natural metric d and if [Formula: see text] is a subset of W, then for each [Formula: see text], there is [Formula: see text] such that [Formula: see text]. Such q is not unique in general but if [Formula: see text] is a …
