Diagrams and reduced decompositions for cominuscule flag varieties and affine Grassmannians.
… associated to cominuscule flag varieties are combinatorially invariant. In the second case, we are able to provide a list of the rationally smooth Schubert varieties in simply laced affine Grassmannians corresponding to types A, D, and E. The results in this case were obtained independently by …
