Quivers, Invariants and Quotient Correspondence
Yi Hu, Sangjib Kim
This paper studies the geometric and algebraic aspects of the moduli spaces of quivers of fence type. We first provide two quotient presentations of the quiver varieties and interp…
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.
A Basis for the Symplectic Group Branching Algebra
Sangjib Kim, Oded Yacobi
The symplectic group branching algebra, B, is a graded algebra whose components encode the multiplicities of irreducible representations of Sp(2n-2,C) in each irreducible represent…
Distributive Lattices, Affine Semigroups, and Branching Rules of the Classical Groups
Sangjib Kim
We study algebras encoding stable range branching rules for the pairs of complex classical groups of the same type in the context of toric degenerations of spherical varieties. By…
