The Incidence Chromatic Number of Toroidal Grids

Eric Sopena, Jiaojiao Wu

An incidence in a graph $G$ is a pair $(v, e)$ with $v \in V (G)$ and $e \in E (G)$ , such that $v$ and $e$ are incident. Two incidences $(v, e)$ and $(w, f)$ are adjacent if $v = w$ , or $…

Coloring the square of the Cartesian product of two cycles

Eric Sopena, Jiaojiao Wu

The square $G^{2}$ of a graph $G$ is defined on the vertex set of $G$ in such a way that distinct vertices with distance at most two in $G$ are joined by an edge. We study the chroma…
