| Abstract: |
| 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. |
