摘要
研究了一般3-正则连通图G的环边连通性和环连通性之间的关系,证明了G的环边连通度等于其环连通度。讨论了G的环连通度与环点连通度之间的关系,指出当G的顶点个数不少于其环连通度的6倍时,其环连通度等于其环点连通度。
The relation between cyclic edge-connectivity and cyclic connectivity of a 3-regular connected graph G is studied.It is proved that the cyclic edge-connectivity of G is equal to its cyclic connectivity.Further,the relation between the cyclic connectivity and the cyclic vertex-connectivity of G is discussed.It is shown that if the vertex number of G is more than 6 times its cyclic connectivity,then its cyclic connectivity is equal to its cyclic vertex-connectivity.
