摘要
讨论非连通图C8(r1,0,r2,0,…,0)∪G的优美性,证明当r1,r2为任意自然数、G是特征为k且缺k+3标号值的交错图(3≤k+3<|E(G)|)时,非连通图C8(r1,0,r2,0,…,0)∪G存在缺标号值k+1的特征为k+5的交错标号,其中C8是具有8个顶点的圈,C8(r1,0,r2,0,…,0)是圈C8的(r1,0,r2,0,…,0)-冠.
The gracefulness of the graph C8 ( r1 ,0, r2 ,0,... ,0) tO G was discussed. It was proved that for any natural numbers rl, r2 when G was balanced bipartite graph with certain conditions , the unconnected graph Cs (q ,0, r2 ,0,... ,0) tO G was balanced bipartite graph.
