在已有减边控制函数定义的基础上,引入了新的控制参数——边度,并利用分类的方法对文献[7]的问题2进行了探索,得到了一般图的关于边数的减边控制数的若干下界.
A new domination parameter-edge degree was introduced on the basis of the definition of minus edge domination function. The question 2 in paper [ 7 ] was investigated using the method of classification, and some lower bounds of the minus edge domination numbers of graphs was obtained.
