摘要 利用Kleitman D J给出的完全二部图的的交叉数cr(_(5,n))=Z(5,n)的结果,分别得到了联图G_(12)∨P_n,G_(15)∨P_n,G_(18)∨P_n的交叉数.同时,给出了目前已知的所有五阶图与路的联图交叉数情况. Using the results of crossing number of complete bipartite graph cr(Ks,n) = Z(5, n) by Kleitman D J, the crossing numbers of the join graph of three specific 5-vertex graphs G12, G15, G18 with the paths Pn are given. In addition, an update to description of join graph of 5-vertex graphs with the paths is given too, whose crossing numbers are known.
