The Dirichlet to Neumann Map For a Cubic Resistor Network Todd J. Holenbeck J. Morrow Relations that characterize the Dirichlet to Neumann map for a cubic network of resistors are given. Using these relations, a parameterization of a subset of Dirichlet to Neumann maps is given (hopefully). 1. Introduction 2. Definitions and Motivations 3.
