Lattice size in higher dimensions

Abdulrahman Alajmi, Sayok Chakravarty, Zachary Kaplan and Jenya Soprunova

Vol. 17 (2024), No. 1, 153–162
Abstract

The lattice size of a lattice polytope is a geometric invariant which was formally introduced in the context of simplification of the defining equation of an algebraic curve, but appeared implicitly earlier in geometric combinatorics. Previous work on the lattice size was devoted to studying the lattice size in dimensions 2 and 3. We establish explicit formulas for the lattice size of a family of lattice simplices in arbitrary dimension.
