Abstract

Let G=(V,E) be a simple and undirected graph with v vertices and e edges. An (a,d)-\emph{edge-antimagic total labeling} is a bijection f from V(G)E(G) to the set of consecutive integers {1,2,,v+e} such that the weights of the edges form an arithmetic progression with initial term a and common difference d. A super (a,d)-\emph{edge antimagic total labeling} is an edge antimagic total labeling f such that f(V(G))={1,,v}. In this paper, we solve some problems on edge antimagic total labeling, such as on paths and unicyclic graphs.

Keywords: Edge antimagic total labeling, super edge antimagic total labeling
