Orbits in $({\mathbb{P}}^r{)}^n$ and equivariant quantum cohomology

Mitchell Lee, Anand Patel, Hunter Spink +1

We compute the $G{L}_{r+1}$-equivariant Chow class of the $G{L}_{r+1}$-orbit closure of any point $(x_1,\dots ,x_n)\in ({\mathbb{P}}^r{)}^n$ in terms of the rank polytope of the matroid…
