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…

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…
