Castelnuovo-Mumford regularity for -avoiding Kazhdan-Lusztig varieties

Colleen Robichaux

We prove the Castelnuovo--Mumford regularity of 321-avoiding Kazhdan--Lusztig varieties can be computed combinatorially in terms of -theoretic skew excited Young diagrams. We pr…

Castelnuovo-Mumford regularity of ladder determinantal varieties and patches of Grassmannian Schubert varieties

Jenna Rajchgot, Colleen Robichaux, Anna Weigandt

We give degree formulas for Grothendieck polynomials indexed by vexillary permutations and -avoiding permutations via tableau combinatorics. These formulas generalize a formu…

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…
