一个特殊5-阶图与圈C_n的联图的交叉数

The Crossing Number of Join Products of a Special 5-Vertex Graph with C_n

联图G∨H表示将G中每个点与H中的每个点连边得到的图.在Klecˇ给出所有3阶图和4阶图与圈Cn的联图的交叉数的基础上,确定了一个5-阶图与圈Cn的联图的交叉数.

A join graph, denoted by G∨H, is illustrated by connecting each vertex of a graph G to each vertex of a graph H. Based on the crossing number of join products of all 3-vertex and 4-vertex graphs with cycle Cn by Klesc, we obtained the crossing number of join products of a special 5-vertex graph with cycle Cn.
