简介：设G是一个图.设g和f是两个定义在V(G)上的整值函数使得对V(G)所有的顶点x有g(x)f(x).图G被称为(g,f,n)-临界图,如果删去G的任意n个顶点后的子图都含有G的(g,f)-因子.本文给出了图是(a,b,n)-临界图几个充分条件.进一步指出这些条件是最佳的.例如,如果对V(G)所有的顶点x和y都有g(x)＜f(x),n+g(x)dG(x)和g(x)/(dG(x)-n)f(y)/dG(y),则G是(g,f,n)-临界图.

简介：在简单图的顶点度和f-因子的关系方面,本文在Tutte定理的基础上给出了图G不存在f-因子时的一个结论.

简介：设G是一个图，具有顶点集V（G）和边集E（G）．设g和f是定义在V（G）上的整数值函数且对每个x∈y（G）有g（x）≤f（x）．本文证明了如下的结果：若G是一个（mg＋kr，mf-kr）一图，且对每个x∈V（G）有g（x）≥r-1，H和G的任意给定的有kr条边的子图，则G中含有一个子图R，使R有（g，f）-因子分解r-正交于H，其中m，k和r是正整数且k〈m.

简介：一个图称为分数（g，f，m）一消去图若删除任意m条边后的剩余子图依然存在分数（g，f）一因子．本文证明若图G的阶为n，1≤n≤g（x）≤f（x）-△≤b-△对任意顶点x∈V（G）成立，δ（G）≥（b-△）（b＋1）/a＋2m,n≥（a＋b）（2（a＋b）＋2m-1）/a＋△且｜NG（x1）∪NG（x2）｜≥（b-△）n/a＋b对任意不相邻顶点x1和x2都成立，则G是分数（g，f，m）-消去图．这个领域并条件在一定程度上是最好的．
