When is a Schubert variety Gorenstein?
Alexander Woo, Alexander Yong
A (normal) variety is Gorenstein if it is Cohen-Macualay and its canonical sheaf is a line bundle. This property, which measures the ``pathology'' of the singularities of a variety…
A formula for K-theory truncation Schubert calculus
Allen Knutson, Alexander Yong
Define a ``truncation'' of a polynomial in as the polynomial with all but the first variables set to zero. In certain good cases, the trunc…
On combinatorics of quiver component formulas
Alexander Yong
Buch and Fulton conjectured the nonnegativity of the quiver coefficients appearing in their formula for a quiver variety. Knutson, Miller and Shimozono proved this conjecture as an…
Schubert Polynomials and Quiver Formulas
Anders Skovsted Buch, Andrew Kresch, Harry Tamvakis +1
The work of Buch and Fulton established a formula for a general kind of degeneracy locus associated to an oriented quiver of type . The main ingredients in this formula are Schu…
Degree Bounds in Quantum Schubert Calculus
Alexander Yong
Fulton and Woodward have recently identified the smallest degree of that appears in the expansion of the product of two Schubert classes in the (small) quantum cohomology ring…
