Asymptotically maximal Schubitopes

Jack Chen-An Chou, Linus Setiabrata

We find a layered permutation $w \in S_{n}$ whose Schubert polynomial $S_{w} (x_{1}, \dots, x_{n})$ has support of size asymptotically at least $n! / 4^{n}$ . This gives precise asympto…

Newton polytopes of fireworks Grothendieck polynomials

Jack Chen-An Chou, Linus Setiabrata

We show that the support of the Grothendieck polynomial $G_{w}$ of any fireworks permutation is as large as possible: a monomial appears in $G_{w}$ if and only if i…
