图的偏度的一种证明方法

A Proof Technique for Skewness of Graphs

Gek L. Chia, Chan L. Lee, Yan Hao Ling

摘要:

图G的偏斜度是指图G中去掉边后成为可平面图的最小边数。通过对图的每条边适当地引入一个权,我们确定了广义Petersen图P(4k,k)的偏斜度,其中奇k至少为9.这为[3]中提出的猜想提供了答案。

英文摘要:

The skewness of a graph G is the minimum number of edges in G whose removal results in a planar graph. By appropriately introducing a weight to each edge of a graph, we determine, among other thing, the skewness of the generalized Petersen graph P(4k, k) for odd k at least 9. This provides an answer to the conjecture raised in [3].
