Sums of Weighted Lattice Points of Polytopes
Jesús A. De Loera, Laura Escobar, Nathan Kaplan +1
We study the problem of counting lattice points of a polytope that are weighted by an Ehrhart quasi-polynomial of a family of parametric polytopes. As applications one can compute…

Newton polytopes and symmetric Grothendieck polynomials
Laura Escobar, Alexander Yong
Symmetric Grothendieck polynomials are inhomogeneous versions of Schur polynomials that arise in combinatorial -theory. A polynomial has saturated Newton polytope (SNP) if every…
