Gelfand $W$ -graphs for classical Weyl groups

Eric Marberg, Yifeng Zhang

A Gelfand model for an algebra is a module given by a direct sum of irreducible submodules, with every isomorphism class of irreducible modules represented exactly once. We introdu…

Gröbner geometry for skew-symmetric matrix Schubert varieties

Eric Marberg, Brendan Pawlowski

Matrix Schubert varieties are the closures of the orbits of $B \times B$ acting on all $n \times n$ matrices, where $B$ is the group of invertible lower triangular matrices. Extendin…

Principal specializations of Schubert polynomials in classical types

Eric Marberg, Brendan Pawlowski

There is a remarkable formula for the principal specialization of a type A Schubert polynomial as a weighted sum over reduced words. Taking appropriate limits transforms this to an…
