| 摘 要： | 一个图称为分数（g,f）－因子消去图，如果去掉图G中的任何一条边e图G仍有一个分数（g,f）－因子。本文分别给出了一个力是分数1－因子消去图和分数2－因子消去图的几个充分条件，并给出一个图有一个分数（g,f）－因子不含给定对集中任何一条边的充要条件。

| Abstract: | A graph G is fractional (g,f)-deleted if deleting any edge of G,there exists a fractional (g,f)-factor.In this paper,we give some sufficient conditions for a graph to be fractional 1-deleted and fractional 2-deleted.We also give a necessary and sufficient condition for a graph to have a fractional (g,f)-factor excluding any edge of a maching. |
