Numerical techniques for conformal mapping onto a rectangle [PDF]

open access: yes, 1986
This paper is concerned with the problem of determining approximations to the function F which maps conformally a simply-connected domain onto a rectangle R, so that four specified points on are mapped Ω∂respectively onto the four vertices of R.

An orthonormalization method for the approximate conformal mapping of multiply-connected domains [PDF]

open access: yes, 1988
We consider the use of an orthonormalization method for constructing approximations to one of the standard conformal maps for multiply-connected domains. The method has been used successfully in [12], but only for the mapping of doubly-connected domains.

Magnetopause as conformal mapping [PDF]

open access: yesAnnales Geophysicae, 2023
An axi-symmetric two-dimensional magnetopause model is constructed by making use of the conformal mapping in the complex plane. The model is an analytic continuation of the power-law damped (or asymptotically elongated) parabolic shape. The complex-plane

The optimal conformal projection for pan-European mapping [PDF]

open access: yesGeodetski Vestnik, 2020
There is an increasing need for pan-European spatial datasets, mainly to support the common European Union policies. This has inevitably raised demands for adopting pan-European cartographic projections to visualize the spatial data.

Pole type singularities and the numerical conformal mapping of doubly-connected domains [PDF]

open access: yes, 1983
Let f be the function which maps conformally a given doubly-connected domain onto a circular annulus, and let Ω H(z) = f '(z) / f(z) - 1/z . In this paper we consider the problem of determining the main singularities of the function H in compl)(Ω∂∪Ω ...

Conformal mapping of the Borel plane: Going beyond perturbative QCD [PDF]

open access: yesPhysical Review D, 2020
The power corrections in the Operator Product Expansion (OPE) of QCD correlators can be viewed mathematically as an illustration of the transseries concept, which allows to recover a function from its asymptotic divergent expansion.

Controlling electromagnetic surface waves with conformal transformation optics

open access: yesCommunications Physics, 2023
The application of transformation optics to the development of intriguing electromagnetic devices can produce weakly anisotropic or isotropic media with the assistance of quasi-conformal and/or conformal mapping, as opposed to the strongly anisotropic ...

Numerical Conformal Mapping with Rational Functions [PDF]

open access: yesComputational methods in Function Theory, 2019
