无限图的笛卡尔积的哈密顿性和连通性
摘要
本文证明了两个连通有向或无向图(至少有一个无限)的笛卡尔积的连通度不小于它们的连通度之和
并讨论了一些特殊图的笛卡尔积的哈密顿分解及哈密顿性。
Abstract
In this paper we show that the connectivity of the cartesian produet of two connected graphs (finite orinfinite)is no less than the sum of their connectivities. Hamiltonian properties of the cartesian product of someparticular graphs are also discussed.
