| 摘 要： | 目前关于积图的交叉数的研究已经推广到六阶图与星图的积图.研究得到了一个特殊六阶图Q与n个孤立点nK_1的联图交叉数,然后通过收缩的方法,得到了Q与星图S_n的积图交叉数.

The Crossing Number of Cartesian Products of the Special Graph on Six Vertices with Stars |
| |
| Abstract: | At present,the research on the crossing number of Cartesian products has been extended to the 6-vertices graph with stars.In this paper,we compute the crossing numbers of join products of the special 6-vertices graph Q with n isolated vertices nK1,then by contraction operations,the crossing number of Cartesian products of Q with stars also have been obtained. |
