Guoyang Zhang · Jilin Normal University Journal · 2007
We present a kind of disconnected graph the union of star St and graph m-C4,and have proved that graph Stp∪m-C4 is a graceful graph when m≥2.We have proved that the union of star St and graph ∪from i=1 to n mi-C4 graph St∪from i=1 to n mi-C4 is a graceful graph when max mi≥3(i=1,2,…,n).
