Convergence of the Zipper algorithm for conformal mapping

  title={Convergence of the Zipper algorithm for conformal mapping},
  author={Donald E. Marshall and Steffen Rohde},
  journal={arXiv: Complex Variables},
In the early 1980's an elementary algorithm for computing conformal maps was discovered by R. K\"uhnau and the first author. The algorithm is fast and accurate, but convergence was not known. Given points z_0,...,z_n in the plane, the algorithm computes an explicit conformal map of the unit disk onto a region bounded by a Jordan curve \gamma with z_0,...,z_n \in \gamma. We prove convergence for Jordan regions in the sense of uniformly close boundaries, and give corresponding uniform estimates… 
Dynamics, Probability, and Conformal Invariance
The study of dynamics in the plane has recently seen a surge in interest due to three recent breakthroughs: the Sullivan-McMullen-Lyubich proof of the Feigenbaum Universality, the introduction by O.
The Loewner differential equation and slit mappings
In his study of extremal problems for univalent functions, K. Lowner [11] (who later changed his name into C. Loewner) introduced the differential equation named after him. It was a key ingredient in
Numerical Solution of the Beltrami Equation
An effective algorithm is presented for solving the Beltrami equation fzbar = mu fz in a planar disk. The algorithm involves no evaluation of singular integrals. The strategy, working in concentric
Conformal Welding of Dendrites
We characterize the laminations that arise from conformal mappings onto planar dendrites whose complement is a John domain. This generalizes the well-known characterization of quasicircles via
Using a Zipper Algorithm to find a Conformal Map for a Channel with Smooth Boundary
The so called geodesic algorithm, which is one of the zipper algorithms for conformal mappings, is combined with a Schwarz–Christoffel mapping, in its original or in a modified form, to produce a co
Computing the Loewner Driving Process of Random Curves in the Half Plane
We simulate several models of random curves in the half plane and numerically compute the stochastic driving processes that produce the curves through the Loewner equation. Our models include models
Shape representation via conformal mapping
This paper discusses some constructions from the theory of conformal mapping which provide ways to represent and compare planar shapes and introduces some results demonstrating how conformal mapped encodes the geometry of a planar domain.
Conformal invariance in two-dimensional turbulence
The simplicity of fundamental physical laws manifests itself in fundamental symmetries. Although systems with an infinite number of strongly interacting degrees of freedom (in particle physics and
Nodal domain statistics for quantum chaotic maps
We study the statistical distribution of nodal domains in the eigenvectors of quantum chaotic maps in the semiclassical limit. For generic quantum maps, which are believed to behave statistically
Monte Carlo comparisons of the self-avoiding walk and SLE as parameterized curves
The scaling limit of the two-dimensional self-avoiding walk (SAW) is believed to be given by the Schramm-Loewner evolution (SLE) with the parameter kappa equal to 8/3. The scaling limit of the SAW


A Multipole Method for Schwarz-Christoffel Mapping of Polygons with Thousands of Sides
A method is presented for the computation of Schwarz--Christoffel maps to polygons with tens of thousands of vertices by the use of the fast multipole method and Davis's method for solving the parameter problem.
