Abstract

Developable surfaces are surfaces in three-dimensional Euclidean space with zero Gaussian curvature. If these surfaces are explicitly defined in the functional form z=f(x,y)\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$z=f(x,y)$$\end{document}, then f is nothing but a solution of the homogeneous Monge–Ampère equation. The main aim of this paper is to classify developable surfaces defined as graphs of weighted-homogeneous functions and to apply the result in economic analysis. We establish a complete classification of weighted-homogeneous production models through associated production surfaces, proving that there exist five classes of weighted-homogeneous production functions exhibiting vanishing Gaussian curvature, generalizing the result established in Chen and Vîlcu (Appl Math Comput 225, 345–351, 2013), where it was stated that only two classes of homogeneous production functions define developable surfaces, namely those having constant return to scale and those defined by binomial functions. We also propose some challenging problems for further research.
