摘要: 该文给出强自同态半群构成并群的图族的特征, 同时文中也明确刻划了其中每个群的单位元.
关键词: 图, 自同态, 半群, 群
Abstract: In this paper, the author gives a characterization for a graph G such that s End(G), the monoid of the strong endomorphisms of G, is the union of groups. In particular, if this is the case, the author explicitly finds the identity element of each group in s End(G).
Key words: Graph, Endomorphism, Semigroup, Group
