摘要
Abstract
The circular chromatic number of a graph is an important parameter of a graph. The distance graph G(Z,D), with a distance set D, is the infinite graph with vertex set Z={0,±1,±2,…} in which two vertices x and y are adjacent iff y-x∈D. This paper determines the circular chromatic numbers of two classes of distance graphs G(Z,Dm,k,k+1) and G(Z,Dm,k,k+1,k+2).关键词
