Let i be a positive integer. We generalize the chromatic number x ( G ) of G and the clique number w(G) of G as follows: The i-chromatic number of G , denoted by x Z ( G ) , is the least number k for which G has a vertex partition V,, V,, . . . , Vk: such that the clique number of the subgraph induc
The cycle graph of a graph G is the edge intersection graph of the set of all the induced cycles of G. G is called cycle-perfect if G and its cycle graph have no chordless cycles of odd length at least five. We prove the statement of the title. 0 1996 John Wiley &
