Ehrhart-Equivalence, Equidecomposability, and Unimodular Equivalence of Integral Polytopes

Fiona Abney-McPeek, Sanket Biswas, Senjuti Dutta +3

Ehrhart polynomials are extensively-studied structures that interpolate the discrete volume of the dilations of integral $n$ -polytopes. The coefficients of Ehrhart polynomials, how…

Ulam Sets in New Settings

Tej Bade, Kelly Cui, Antoine Labelle +1

The classical Ulam sequence is defined recursively as follows: $a_{1} = 1$ , $a_{2} = 2$ , and $a_{n}$ , for $n > 2$ , is the smallest integer not already in the sequence that can be written uni…

Exponents of Jacobians of Graphs and Regular Matroids

Hahn Lheem, Deyuan Li, Carl Joshua Quines +1

Let $G$ be a finite undirected multigraph with no self-loops. The Jacobian $Jac (G)$ is a finite abelian group associated with $G$ whose cardinality is equal to the n…
