英文摘要
In this research, we interpreted a hamiltonian cycle as a 2-factor with one component, and investigated conditions which differentiate the existence of a hamiltonian cycle and that of a 2-factor, or more generally, which give information on the number of components in a 2-factor. We chose Dirac's condition, the Chvatal-Erdos condition and conditions based on forbidden subgraphs. We discovered that while neither Dirac's condition nor the Chvatal-Erdos condition gives any information on the number of components in a 2-factor, there is a notable difference between forbidden subgraphs forcing the existence of a hamiltonian cycle and those forcing the existence of a 2-factor.
