THE GRACEFUL LABELING OF THE UNCONNECTED GRAPH C12(r1,0,r2,0,…,r6,0)∪Fk,4
摘要
Abstract
The gracefulness of the unconnected graph C12(r1,0,r2,0,…,r6,0)∪Fk,4 is discussed. Furthermore, we prove the following results:For any natural number a,k,ri(i=1,2,…,6),if r5=r6=0,k=3,r6=a,r5≥2-a,k=4;r6≥4,k=5, then the unconnected graphs C12(r1,0,r2,0,…,r6,0)∪Fk,4 are balanced bipartite graph.关键词
