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.

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