摘要: G是一个图.k是自然数.图G的一个k-正则支撑子图称为G的一个k-因子.若对于G的每条边e.G-e都存在一个k-因子,则称G是一个k-消去图.该文得到了一个图是k-消去图的若干充分条件,推广了文[2-4]中有关结论.

关键词: 图, 支撑子图, k-因子, k-消去图

Abstract: If G is a graph and k is a positive integer,then a k-factor of G is a k-regular spanning subgraph. G is called a k-deleted graph if G-e has a k-factor for each edge e. In this paper, we obtain several new results for k-deleted graphs.

Key words: Graph, Spanning subgraph, k-factor, k-deleted graph
