✦ Synopsis


It is proved that if G is a planar graph with total (vertex-edge) chromatic number Ο‡ , maximum degree and girth g, then Ο‡ = + 1 if β‰₯ 5 and g β‰₯ 5, or β‰₯ 4 and g β‰₯ 6, or β‰₯ 3 and g β‰₯ 10. These results hold also for graphs in the projective plane, torus and Klein bottle.

The odd-girth of a graph is the length of a shortest odd circuit. A conjecture by Pavol Hell about circular coloring is solved in this article by showing that there is a function f ( ) for each : 0 < < 1 such that, if the odd-girth of a planar graph G is at least f ( ), then G is (2 + )-colorable.

Suppose G and H are graphs. We say G is H-colorable if there is a homomorphism (edge-preserving vertex mapping) from G to H. We say a graph G is uniquely H-colorable if there is an onto homomorphism c from G to H, and any other homomorphism from G to H is the composition o o c of c with an automorph

## Abstract In 1959, even before the Four‐Color Theorem was proved, GrΓΆtzsch showed that planar graphs with girth at least 4 have chromatic number at the most 3. We examine the fractional analogue of this theorem and its generalizations. For any fixed girth, we ask for the largest possible fraction
