Problems on the Triangular Lattice
Gaston A. Brouwer, Jonathan Joe, Abby A. Noble +1
In this work, we consider a number of problems defined on the triangular lattice with rows, which we will denote as . Define a \textit{proper coloring} to be an assignment…
Odd Vector Cycles in
Gaston A. Brouwer, Jonathan Joe, Matt Noble
Given positive integers and , define to be the minimum odd number of vectors, each of magnitude , that together sum to the zero vector. In…
A Triangle-free, 4-chromatic Euclidean Distance Graph Scavenger Hunt!
Jonathan Joe, Matt Noble
For , define to be the graph whose set of vertices is the rational space , where two vertices are adjacent if and only if they are a Eucli…
Embedding Euclidean Distance Graphs in and
Matt Noble
For , positive integer , and , let be the graph whose vertex set is where any two vertices are adjacent if and only if they are…
On Rainbow Cycles and Proper Edge Colorings of Generalized Polygons
Matt Noble
An edge coloring of a simple graph is said to be \textit{proper rainbow-cycle-forbidding} (PRCF, for short) if no two incident edges receive the same color and for any cycle in…
Answer to an Isomorphism Problem in
Matt Noble
For and , denote by the graph with vertex set with any two vertices being adjacent if and only if they are at a Euclidean distance …
Assorted Musings on Dimension-critical Graphs
Matt Noble
For a finite simple graph , say is of dimension , and write , if is the smallest integer such that can be represented as a unit-distance graph in $\m…
