Using paralled mathematic induction method , it proved that maximum plane graph with any degree which is contructed by way of “ adding point within plane “ or “ adding point at the edge “ is 4 - colorable 運用“并行(或平行)數學歸納法”證明了由“面內加點”或“邊上加點”方法所構造的任意階極大平面圖是可四著色的。

In chapter 2 , a relationship between three types of oriented triple systems mts , dts , hts is discussed , i . e . , if the block incidence graph of an mts ( v , a ) is 3 edge - colorable , then we can get three disjoint dts ( v , ) s and four disjoint hts ( v , ) s 第二章討論三類有向三元系mts , dts , hts之間的一種關聯關系:如果一個mts ( v , )的區組關聯圖是3 -邊可染色的,則可得到三個不相交的dts ( v , )及四個不相交的hts ( v , ) ,且對應區組的基礎集均一致。

Markov ' s inequality and four kinds of lovasz local lemma , and give different applications in hypergraphs with these probabilistic methods , we find different conditions for a hypergraph to be 2 - colorable with some kinds of thinkings ) sz局部引理的內容,給出了這幾種概率方法在超圖上的應用,用幾種思路找到了超圖存在2 -可染色的不同條件,其中著重對一般形式的lov (
