A Schrödinger network is a suitable infinite graph on which certain potential‐theoretic aspects of the discrete Schrödinger equation can be studied. It is shown that the positive solutions of this discrete equation can be represented as integrals. The Cartesian product of Schrödinger networks, which has a bearing on Markov chains, is investigated. Also, we give a characterization of minimal positive harmonic functions on the the Cartesian product of Schrödinger networks.
