Abstract.

For a graph G, with the vertex set V(G) and the edge set E(G) an edge-magic total labeling is a bijection f from V(G) E(G) to the set of integers {1,2,,|V(G)|+|E(G)|} with the property that f(u)+f(v)+f(uv)=k for each uvE(G) and for a fixed integer k. An edge-magic total labeling f is called super edge-magic total labeling if f(V(G))={1,2,, |V(G)|} and f(E(G))={|V(G)|+1, |V(G)|+2,, |V(G)|+ |E(G)|}. In this paper we construct the expanded super edge-magic total graphs from cycles Cn, generalized Petersen graphs and generalized prisms.



Keywords: Edge-magic; super edge-magic; magic-sum.
