W4 ∨ Cn的交叉数
THE CROSSING NUMBER OF W4 ∨ Cn

本文研究了五阶图与圈图的联图交叉数.利用假设法和比较法等方法,得到了W4 ∨ Cn的交叉数为Z(5,n)+n+？(n)/(2)」+4,并推广了联图交叉数的结果与方法.
In the paper, we study the crossing numbers of the join graph of order flve with cycle. Based on the hypothesis and comparison, we get the results of the crossing number of W4 ∨ Cn is Z(5,n) + n + ？(n)/(2)」 + 4, which extends the results and methods of the crossing numbers of the join graph
