The 6 Vertex Model and Schubert Polynomials [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We enumerate staircases with fixed left and right columns. These objects correspond to ice-configurations, or alternating sign matrices, with fixed top and bottom parts.

Tableau formulas for skew Schubert polynomials [PDF]
, 2023 The skew Schubert polynomials are those which are indexed by skew elements of the Weyl group, in the sense of arXiv:0812.0639. We obtain tableau formulas for the double versions of these polynomials in all four classical Lie types, where the tableaux ...

Which Schubert varieties are local complete intersections? [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We characterize by pattern avoidance the Schubert varieties for $\mathrm{GL}_n$ which are local complete intersections (lci). For those Schubert varieties which are local complete intersections, we give an explicit minimal set of equations cutting out ...

Schur polynomials and matrix positivity preservers [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 A classical result by Schoenberg (1942) identifies all real-valued functions that preserve positive semidefi- niteness (psd) when applied entrywise to matrices of arbitrary dimension.

A Murgnahan-Nakayama rule for Schubert polynomials [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 We expose a rule for multiplying a general Schubert polynomial with a power sum polynomial in $k$ variables. A signed sum over cyclic permutations replaces the signed sum over rim hooks in the classical Murgnahan-Nakayama rule. In the intersection theory
