Lattice Points in the Newton Polytopes of Key Polynomials

Neil J. Y. Fan, Peter L. Guo, Simon C. Y. Peng +1

We confirm a conjecture of Monical, Tokcan and Yong on a characterization of the lattice points in the Newton polytopes of key polynomials.

Vertices of Schubitopes

Neil J. Y. Fan, Peter L. Guo

Schubitopes were introduced by Monical, Tokcan and Yong as a specific family of generalized permutohedra. It was proven by Fink, Mészáros and St.Dizier that Schubitopes are the…

Upper Bounds of Schubert Polynomials

Neil J. Y. Fan, Peter L. Guo

Let $w$ be a permutation of ${1, 2, \dots, n}$ , and let $D (w)$ be the Rothe diagram of $w$ . The Schubert polynomial $S_{w} (x)$ can be realized as the dual character of th…

Set-valued Rothe Tableaux and Grothendieck Polynomials

Neil J. Y. Fan, Peter L. Guo

The notion of set-valued Young tableaux was introduced by Buch in his study of the Littlewood-Richardson rule for stable Grothendieck polynomials. Knutson, Miller and Yong showed t…
