Query: On the Birational Geometry of Schubert Varieties   We classify all Q-factorializations of (co)minuscule Schubert varieties by
using their Mori dream space structure. As a corollary we obtain a description
of all IH-small resolutions of (co)minuscule Schubert varieties generalizing
results of Perrin. We improve his results by including algebraically closed
fields of positive characteristic and cominuscule Schubert varieties. Moreover,
the use of Q-factorializations and Mori dream spaces simplifies the arguments
substantially.
