摘要 指出了一类边裂图SEP(K1,n,f)与图K1,n的边优美性的差异.得到了对任意自然数m>0,SPE(K1,4m+1,f)不是边优美的,以及SEP(K1,n,f)是边优美图的充要条件. The differences of the edge-gracefulness between SEP(K1,n, f) and Kl.n are pointed out. We obtain the SPE(K1,4m+1, f) is not edge-graceful for any integer m 〉 0, then give the necessary and sufficient condition for SEP(K1,n, f) to be edge-graceful.
