摘要 在图的边覆盖染色中边覆盖临界图的构造问题一直是研究的热点和难题.给出了一类边覆盖临界图的构造方法.对于任意给定的最小度δ,利用该方法可以构造出相应的一类边覆盖临界图. The construction of edge covered critical graphs is an important problem in the edge covercoloring of graphs. In this paper, method to construct a class of edge covered critical graphs is given. For any minimum degree δ of graph, a class of edge covered critical graphs can be constructed.
