摘要
边对称图〈H,G〉含有子图H和G,使得删去边子集E(H)的所有边后,剩余图的任何分支均同构于G.刻划了一类对称图的基本性质,推广边魔幻全标号到广义边魔幻全标号.利用可算法化的构造性证明,得到大型的具有(广义)边魔幻全标号的对称图.
An edge-symmetric graph ( H, G) contains subgraphs H and G such that the deletion of edges of E(H) results in a disconnected graph in which every component is isomorphic to G. In this paper basic properties of a special class of edge-symmetric graphs are inverstigated, the notion of edge-magic total labelling is generalized to that of generalized edge-magic total labelling, some edgesymmetric graphs with large scale having (generalized) edge-magic total labellings are obtained and proved algorithmically.
