Discrete Potential Theory on Schrödinger Products
Main Article Content
Abstract
This article develops a discrete potential-theoretic framework for Cartesian products of infinite Schrödinger networks. We introduce the notion of product Schrödinger networks and define separately \(q\)-supermean and separately \(q\)-potential functions, establishing their structural and comparison properties. Integral representation theorems and a Riesz-type decomposition are proved for non-negative separately \(q\)-supermean functions on product networks. Furthermore, we present a classification of product Schrödinger networks based on bounded and unbounded mean behavior, showing how the \(q\)-mean (\(q\)-harmonic) and potential-theoretic nature of the product network are determined by the corresponding properties of the individual factor networks.
