An excluded minor theorem for the 6-wheel

Zijun Chen, Yuqi Xu, Weihua Yang

For each integer $n \geq 3$ , the wheel graph $W_{n}$ is defined as the graph obtained by connecting a single vertex to all vertices of a cycle of length $n$ . In particular, $W_{6}$ can…

A characterization of 4-connected graphs with no 6-wheel minor

Zijun Chen, Yuqi Xu, Weihua Yang

For each integer $n \geq 3$ , let $W_{n}$ denote the wheel graph obtained by connecting a single vertex to all vertices of a cycle of length $n$ . In particular, $W_{6}$ is obtained from…
