Three combinatorial formulas for type A quiver polynomials and K-polynomials
Abstract
We provide combinatorial formulas for the multidegree and K-polynomial of an
arbitrarily oriented type A quiver locus. These formulas are generalizations of
three of Knutson-Miller-Shimozono's formulas from the equioriented setting; in
particular, we prove the K-theoretic component formula conjectured by Buch and
Rimányi.
