Extensions of Edge Graceful Labeling of Graphs

Abstract

This work deals with graph labeling. All the graphs considered newlinehere are finite and undirected unless otherwise specified. The terms not newlinedefined here are used in the sense of Harary [12]. newlineA graph labeling is an assignment of integers to the vertices or newlineedges or both subject to certain conditions. If the domain of the mapping newlineis the set of vertices (or edges) then the labeling is called a vertex newlinelabeling (or an edge labeling). newline
