从生成林到边子集

From spanning forests to edge subsets

Martin Trinks

摘要:

我们给一些深入了解Tutte的定义内部和外部活跃的边缘跨越森林。也就是说,我们证明,每一个边缘子集可以构造从边缘的恰好一个生成森林删除一个唯一的子集的内部活动的边缘和添加一个唯一的子集的外部活动的边缘。

英文摘要:

We give some insight into Tutte's definition of internally and externally active edges for spanning forests. Namely we prove, that every edge subset can be constructed from the edges of exactly one spanning forest by deleting a unique subset of the internally active edges and adding a unique subset of the externally active edges.
