Abstract
Which graphs admit an integer valued harmonic function which is injective and surjective onto Zd Such a function, which we call harmonic labeling, is constructed when the graph is the lattice Zd. It is shown that for any finite graph G containing at least one edge, there is no harmonic labeling of G×Z. Further discussion and open problems are presented.
