Abstract: | The Erd?s–Lovász Tihany conjecture asserts that every graph G with ) contains two vertex disjoint subgraphs G 1 and G 2 such that and . Under the same assumption on G , we show that there are two vertex disjoint subgraphs G 1 and G 2 of G such that (a) and or (b) and . Here, is the chromatic number of is the clique number of G , and col(G ) is the coloring number of G . |
