Bumpless pipe dreams and alternating sign matrices
Anna Weigandt
In their work on the infinite flag variety, Lam, Lee, and Shimozono (2018) introduced objects called bumpless pipe dreams and used them to give a formula for double Schubert polyno…
Degrees of symmetric Grothendieck polynomials and Castelnuovo-Mumford regularity
Jenna Rajchgot, Yi Ren, Colleen Robichaux +2
We give an explicit formula for the degree of the Grothendieck polynomial of a Grassmannian permutation and a closely related formula for the Castelnuovo-Mumford regularity of the…
Prism tableaux for alternating sign matrix varieties
Anna Weigandt
A prism tableau is a set of reverse semistandard tableaux, each positioned within an ambient grid. Prism tableaux were introduced to provide a formula for the Schubert polynomials…
Schubert polynomials, 132-patterns, and Stanley's conjecture
Anna Weigandt
Motivated by a recent conjecture of R. P. Stanley we offer a lower bound for the sum of the coefficients of a Schubert polynomial in terms of -pattern containment.
