By connecting the 5 vertices of K5 to other n vertices, we obtain a special family of graph denoted by Hn. This paper proves that the crossing number of Hn is Z(5, n) +2n+ [n/2] +1, and the crossing number of Car... By connecting the 5 vertices of K5 to other n vertices, we obtain a special family of graph denoted by Hn. This paper proves that the crossing number of Hn is Z(5, n) +2n+ [n/2] +1, and the crossing number of Cartesian products of K5 with star Sn is Z(5, n) + 5n + [n/2] + 1. 展开更多
