Circular Chromatic Numbers and Fractional Chromatic Numbers of Distance Graphs
Copyright policy )Circular Chromatic Numbers and Fractional Chromatic Numbers of Distance Graphs
This paper studies the circular (or star) chromatic numbers and fractional chromatic numbers of distance graphs \(G(Z, D)\) for various sets \(D\) (being the graph with vertex set a subset of the integers, and two vertices \(x\), \(y\) being adjacent iff \(| x-y|\in D\)). Various specific cases are calculated, including all cases when \(| D|= 2\).
