不超过1的偶因子指标

The Even Factor Index at Most 1 of Graphs

基于2-因子指标大于等于2和偶因子指标大于等于1的研究结果都已经比较完善。鉴于此,主要考虑了不超过1的2-因子指标和等于0的偶因子指标,并给出了与之相关的若干结论。

The results on 2-factor index at least 2 and even factor index at least 1 have been more perfect by now.In view of this reason,we primarily consider the 2-factor index at most 1 and even factor index equal 0,and give some conclusions about these two problems.
