摘要
分别给出分数 (g,f ) - 2 -覆盖图和分数 (g,f ) - 2 -消去图的概念 ,以及一个图是分数 (g,f ) - 2 -覆盖图和分数 (g,f ) - 2 -消去图的若干充分条件 .
In this paper,the fractional (g,f)-2-covered graph and the fractional (g,f)-2-deleted graph are defined,and some sufficient conditions for a graph to be fractional (g,f)-2-covered and fractional (g,f)-2-deleted are given.
