Combinatorics and Graph Theory
Anna Weigandt from University of Michigan will be speaking.
The presentation is titled "Transition on Grothendieck Polynomials."
This is a virtual meeting that takes place via Zoom.
The description of the event is as follows:
Using anti-diagonal Gröbner geometry, Knutson and Miller explained how Grothendieck polynomials arise as K-polynomials of matrix Schubert varieties. We will discuss how Lascoux's transition equations for Grothendieck polynomials can be realized geometrically through "almost anti-diagonal" Gröbner degeneration of matrix Schubert varieties. In particular, under this strange term order, Fulton's generators form a Gröbner basis. Our proof involves studying the lattice of alternating sign matrices. more information...
