From Schubert Varieties to Doubly-Spherical Varieties
Horospherical Schubert varieties are determined. It is shown that the
stabilizer of an arbitrary point in a Schubert variety is a strongly solvable
algebraic group. The connectedness of this stabilizer subgroup is discussed.
Moreover, a new family of spherical varieties, called doubly spherical
varieties, is introduced. It is shown that every nearly toric Schubert variety
is doubly spherical.
