Wen Yi-hui · Journal of Qufu Normal University · 2008
In this paper,the edge-gracefulness,super edge-gracefulness and Q(a)P(b)-super edge-gracefulness of(P,P+1)-graphs are discussed,and point out that there is no such graph that is edge-graceful、super edge-graceful and Q(a)P(b)-super edge-graceful at the same time in(P,P+1)-graphs,some results including that there are no including relationships between edge-gracefulness and super edge-gracefulness are obtained.
