在本文中,我们证明了一个三次图的边集总是可以划分成10个子集,每一个子集诱导图中的一个匹配。这个结果是Erdos和Nesetril的一个一般猜想的特殊情况:对于每个d ≥ 3,最大度d的图的边集总是可以划分为右垂直的5d ~ 2/4个左垂直子集,每个子集都诱导一个匹配。
In this paper, we show that the edge set of a cubic graph can always be partitioned into 10 subsets, each of which induces a matching in the graph. This result is a special case of a general conjecture made by Erdos and Nesetril: For each d greater-than-or-equal-to 3, the edge set of a graph of maximum degree d can always be partitioned into right perpendicular 5d2/4 left perpendicular subsets each of which induces a matching.
