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
## Abstract Given a simple plane graph __G__, an edgeβface __k__βcoloring of __G__ is a function Ο : __E__(__G__) βͺ __F__(G)βββ {1,β¦,__k__} such that, for any two adjacent or incident elements __a__, __b__ β __E__(__G__) βͺ __F__(__G__), Ο(__a__)ββ βΟ(__b__). Let Ο~e~(__G__), Ο~ef~(__G__), and Ξ(__G_
We prove that, for any pair of integers k, l 1, there exists an integer N(k, l ) such that every graph with chromatic number at least N(k, l ) contains either K k or an induced odd cycle of length at least 5 or an induced cycle of length at least l.
For each pair k, rn of natural numbers there exists a natural number f(k, rn) such that every f ( k , m)-chromatic graph contains a k-connected subgraph of chromatic number at least rn.
