摘要 阶数不大于5的有关的联图的交叉数已经有了一些确切结论,文中更进一步研究六阶图与路的联图的交叉数,并确定了S5∨Pn以及其他5个六阶图G∨Pn的交叉数. There are several known exact results on the crossing numbers for join products for small graphs of order at most five. This paper further studies the join of graphs, and give the exact values of crossing numbers for join products S5 V Pn and G V Pn for other five graphs G of order six.
