具有Kempe染色的线图的根完全子式

Rooted complete minors in line graphs with a Kempe coloring

Matthias Kriesell, Samuel Mohr

摘要:

如果有限图的顶点着色使得任意两个色类的并集导出连通图,则对于每个顶点集$T$,存在一个完全子图使得$T$包含每个分支集的一个成员.在这里,我们证明的声明线图。

英文摘要:

It has been conjectured that if a finite graph has a vertex coloring such that the union of any two color classes induces a connected graph, then for every set $T$ of vertices containing exactly one member from each color class there exists a complete minor such that $T$ contains exactly one member from each branching set. Here we prove the statement for line graphs.
