I. Cahit calls a graph H-cordial if it is possible to label the edges with the numbers from the set{1,-1} in such a way ......

Cahit首次提出H-cordial图概念,先定义每条边的标号为{-1,1},由边的标号导出顶点v的标号——与顶点v关联的所有边的标号之和.若存......

In this paper we prove that the join of two path graphs, two cycle graphs, Ladder graph and the tensor product are H2-co......

In this paper we prove that the complete bipartite graph kmn where m and n are even, join of two cycle graphs cn and cm ......
