摘要
介绍了图的简单扩容图和完全扩容图的概念.给出扩容图的一个等价定义,构造了一类新图———极大扩容图,并证明了它是Hedetniemi猜想成立的无限图类.
The concept of the simple expansion and maximum expansion graph is introduced.A equivalent definition of the expansion graph is given.Constructed a new maximum expansion graph and proved that Hedetniemi's Conjecture is true on the new infinite graphs.
