Abstract:   Using forbidden subgraphs condition to guarantee a graph to have Hamiltonian properties becomes  very popular recently. There are some famous Open problems,such as the very famous long-standing Matthews-Sumner conjecture that every 4-connected claw-free graph is Hamiltonian and so on. In this talk, we shall present this kind of problems and specially we present the updated results on the relationship between forbidden subgraphs and Hamiltonian properties.
