Abstract: Let h(G) denote the largest t such that G contains Kt as a minor, chi(G) the chromatic number of G respectively. In 1943, Hadwiger conjectured that h(G)geqchi(G) for any graph G. In this paper, we will prove Hadwiger's Conjecture holds for H-free graphs with independence number two, where H is any one of 4 given graphs.
