Circular Coloring the Plane

SIAM Journal on Discrete Mathematics, 2007
The unit distance graph $\mathcal{R}$ is the graph with vertex set $\mathbb{R}^2$ in which two vertices (points in the plane) are adjacent if and only if they are at Euclidean distance $1$. We prove that the circular chromatic number of $\mathcal{R}$ is at least $4$, thus improving the known lower bound of $32/9$ obtained from the fractional chromatic ...

Coloring a Family of Circular Arcs

SIAM Journal on Applied Mathematics, 1975
This paper presents a collection of results about coloring a family of circular arcs. We prove that the strong perfect graph conjecture is valid for circular-arc graphs. We give some upper bounds on the number of colors needed to color various families of arcs.
