Resum
A graph G of order p and size q is edge-magic if there is a bijective function f : V(G) ¿ E(G) ¿ {i}p+q i=1 such that f(x) + f(xy) + f(y) = k, for all xy ¿ E(G). The function f is an edge-magic labeling of G and the sum k is called either the magic sum, the valence or theweight of f. Furthermore, if f(V(G)) = {i}p i=1 then f is a super edge-magic labeling of G. In this paper we study the valences that can be attained by (super) edge-magic labelings of some families of graphs
