Standard Monomial Theory of RR varieties
Philip Foth, Sangjib Kim
We construct the RR varieties as the fiber products of Bott-Samelson varieties over Richardson varieties. We study their homogeneous coordinate rings and standard monomial theory.

Row Convex Tableaux and Bott-Samelson Varieties
Philip Foth, Sangjib Kim
By using row convex tableaux, we study the section rings of Bott-Samelson varieties of type A. We obtain flat deformations and standard monomial type bases of the section rings. In…
