In this paper, we prove that if a claw-free graph G with minimum degree @d>=4 has no maximal clique of two vertices, then G has a 2-factor with at most (|G|-1)/4 components. This upper bound is best possible. Additionally, we give a family of claw-free graphs with minimum degree @d>=4 in which every 2-factor contains more than n/@d components. |
