SOME SUPER EDGE-MAGIC GRAPHS A. Sinna∗, P. Patarakitvanit†, S. Singhun‡, N. Udomsub§ and W. Hemakul¶ Department of Mathematics, Faculty of Science, Chulalongkorn University, Bangkok 10330, Thailand

Abstract A (p, q)-graph G is super edge-magic if there exists a bijective function f : V (G) ∪ E(G) → {1, 2, ..., p + q} such that f (u) + f (v) + f (uv) is a constant for any edge uv ∈ E(G) and f (V (G)) = {1, 2, ..., p}. We show some new super edge-magic graphs and a new construction of super edgemagic graphs from the old ones is presented.

Keywords : Graph, Super edge-magic
