摘要: 构造了2类新图2-2nK5和2-nZ5,用嵌套递推的方法,得到了这2类新图的完美匹配数的2个递推关系式及其通解, 从而得到了这2类图的完美匹配数目的计算公式.Abstract: Two new graphs 2-2nK5 and 2-nZ5 are constructed. Using the nested recursive method, two recursive relations of the perfect matching numbers of graphs 2-2nK5 and 2-nZ5 are obtained, and then the two recursive general solutions are solved. Thus, the formula for calculating the perfect matching number of these two types of graphs is obtained.
