摘要
The relation between Hamiltonicity and toughness of a graph is a long standing research problem. The paper studies the Hamiltonicity of the Cartesian product graph G1□ G2 of graphs G1 and G2 satisfying that G1 is traceable and G2 is connected with a path factor. Let Pn be the path of order n and H be a connected bipartite graph. With certain requirements of n, we show that the following three statements are equivalent: (i) Pn□ H is Hamiltonian; (ii) Pn□ H is 1-tough; and (iii) H has a path factor.
