• Φ-GRACEFUL LABELING OF SOME GRAPHS
Abstract
Let be a graph .The-graceful labeling of a graph with verticesand edges is a injective a function such that the induced function is given by , the resulting edge labels are distinct. In this paper we prove result – graceful labeling of Thorn ring graph, Cycle with twin chords.
Keywords
Thorn ring graph, Cycle ( C_n ) with twin chords.
