On the crossing number of join of the wheel on six vertices with the discrete graph
Štefan Berežný, Michal Staš · Carpathian Journal of Mathematics · 2020
The main aim of the paper is to give the crossing number of join product for the wheel on six vertices, and consisting of isolated vertices. In the proofs, it will be extend the idea of the minimum numbers of crossings between two different subgraphs from the family of subgraphs which do not cross […]
