This paper studies circular chromatic numbers and fractional chromatic numbers of distance graphs G(Z , D) for various distance sets D. In particular, we determine these numbers for those D sets of size two, for some special D sets of size three, for

The oriented chromatic number χ o ( G) of an oriented graph G = (V, A) is the minimum number of vertices in an oriented graph H for which there exists a homomorphism of G to H. The oriented chromatic number χ o (G) of an undirected graph G is the maximum of the oriented chromatic numbers of all the

## Abstract The star‐chromatic number of a graph, a concept introduced by Vince, is natural generalization of the chromatic number of a graph. We point out an alternate definition of the star‐chromatic number, which sheds new light on the relation of the star‐chromatic number and the ordinary chrom
