摘要
研究了坌m,t∈N*图S m∪S2t的边幻和标号,得到了两种不同的边幻和算法A和B,给出了坌m,t∈N*图S m∪S2tt是具有边幻和常数C1=4+4m+5t和C2=5+2m+7t的边幻和图,其中图S m是具有m+1个顶点的星图,图S2t具有2t+1个顶点的星图,图S m∪S2t表示图S m和图S2t的并图.
In this paper, the edge-magic total labeling of graphs SmUS2t is studied. Two different edge-magic total labeling algorithms A and B for Vm,t∈N＊ are obtained. All the graphsare SmUS2t the edge-magic total labeling graphs with the edge-magic constant C1=4＋4m＋5t and edge-magic constant C2=5 ＋2m＋7t. The graphs Sm denote star graphs with m ＋ 1 nodes and the graphs S2t, are star graphs with 2t ＋ 1 nodes, respectively. The graphs SmUS2t, stand for the union granhs Sm and graphs S2t.
