dedicated to professor w. t. tutte on the occasion of his eightieth birthday Let S be an orientable surface other than the sphere and let k be a natural number. Then there are infinitely many k-color-critical graphs on S if and only if 3 k 5. In particular, if k 5, then there exists a polynomially

A graph G is called k-critical if x(G) = k and x(G -e) -C x(G) for each edge e of G, where x denotes the chromatic number. T. Gallai conjectured that every k-critical graph of order n contains at most n complete (kl)-subgraphs. In 1987, Stiebitz proved Gallai's conjecture in the case k = 4, and in 1
Given a property P, graph G. and k 2 0, a P k-coloring is a function 7r: V(G) + { I , ... , k) such that the subgraph induced by each color class has property P; x ( G : P ) is the least k, for which G has a P k-coloring. We investigate here the theory of P colorings. Generalizations of the wellknow
