关于完全图的零和完美匹配的存在性

On the Existence of Zero-Sum Perfect Matchings of Complete Graphs

Teeradej Kittipassorn, Panon Sinsap

摘要:

本文证明了:给定一个2-边着色完全图$K_{4n}$,若每种颜色的边数相同,则总能找到每种颜色的边数相等的完美匹配.这解决了Caro、Hansberg、Lauri和Zarb提出的问题。Ehard、Mohr和Rautenbach也独立解决了这个问题。

英文摘要:

In this paper, we prove that given a 2-edge-coloured complete graph $K_{4n}$ that has the same number of edges of each colour, we can always find a perfect matching with an equal number of edges of each colour. This solves a problem posed by Caro, Hansberg, Lauri, and Zarb. The problem is also independently solved by Ehard, Mohr, and Rautenbach.
