Area-Preserving Parameterization: Variational Principle, Gradient Flow, and Discrete Approximation

Area-preserving parameterizations are used in applications where relative surface areas must be preserved. We study this problem through the stretch energy. For orientation-preserving diffeomorphisms between compact Riemannian 2-manifolds of equal total area, we show that the stretch energy is characterized by the vari...
