1、中文摘要论文题目(汉文)图的关联图的边染色论文题目(外文)TheProperEdgeColoringonSomeclassesofIncidenceGraphs图的关联图的边染色中文摘要张忠辅等人在2000年提出了图的关联图的概念,研究了图的关联图的性质和一些特殊图的关联图的正常边染色.并在此基础上提出了图的关联图的边染色猜想:每个简单图的关联图都是第一类图,即简单图的关联图的边色数等于的最大度.图的关联图是一种特殊的运算图,具有较为复杂的结构,确定其边色数是比较困难的.本文在研究关联图结构的基础上,将所研究图的关联图分解成两
2、个边不交的生成子图,然后利用数学归纳法或构造染色的方法确定关联图的边色数.证明了正则二部图、完全二部图、特殊的树、图、一类广义图和几类冠图的关联图都是第一类图,验证了这些图的关联图满足图的关联图的边染色猜想.主要结果如下:(1)设为正则二部图或完全二部图,则.(2)设是具有最大度的树,为的一个最大度点.若,则树的关联图是第一类图.其中,.(3)具有相邻最大度顶点的树的关联图和最大度小于等于4的树的关联图均是第一类图.(4)设图是图,则;设图是广义图,若的两个度点不相邻,则.(5)设是具有最大度的树的冠图,若具有相邻最大度顶点,
