A construction method for discrete constant negative Gaussian curvature surfaces

This article is an application of the author’s paper about a construction method for discrete constant negative Gaussian curvature surfaces, the nonlinear d’Alembert formula. The heart of this formula is the Birkhoff decomposition, and we give a simple algorithm for the Birkhoff decomposition. As an application, we draw figures of discrete constant negative Gaussian curvature surfaces given by this method.
