摘要

风筝图是四个顶点上去掉一条边的完整图。研究证明,每个没有风筝子图的平面图都可以划分为两个诱导森林。这解决了 Raspaud 和 Wang 在 2008 年提出的一个猜想。

Partitioning kite-free planar graphs into two forests

A kite is a complete graph on four vertices with one edge removed. It is proved that every planar graph without a kite as subgraph can be partitioned into two induced forests. This resolves a conjecture of Raspaud and Wang in 2008.
