Dessins d’enfants, Seiberg-Witten curves and conformal blocks

open access: yesJournal of High Energy Physics, 2021
We show how to map Grothendieck’s dessins d’enfants to algebraic curves as Seiberg-Witten curves, then use the mirror map and the AGT map to obtain the corresponding 4d N $$ \mathcal{N} $$ = 2 supersymmetric instanton partition functions and 2d Virasoro ...

A study of horizontally weakly conformal maps and their distributions [PDF]

open access: yesریاضی و جامعه, 2023
The aim of this paper is to consider horizontally weakly conformal maps which have been studied in [P. Baird and J. C. Wood, Harmonic morphisms between Riemannian manifolds, London Mathematical Society Monographs.

Nonlinear automorphism of the conformal algebra in 2D and continuous T T ¯ $$ \sqrt{T\overline{T}} $$ deformations

open access: yesJournal of High Energy Physics, 2022
The conformal algebra in 2D (Diff(S 1)⨁Diff(S 1)) is shown to be preserved under a nonlinear map that mixes both chiral (holomorphic) generators T and T ¯ $$ \overline{T} $$ .

Existence and Stability of α−Harmonic Maps

open access: yesJournal of Mathematics, 2022
In this paper, we first study the α−energy functional, Euler-Lagrange operator, and α-stress-energy tensor. Second, it is shown that the critical points of the α−energy functional are explicitly related to harmonic maps through conformal deformation.

Some results and examples of the biharmonic maps with potential

open access: yesArab Journal of Mathematical Sciences, 2018
In this paper, we will study the class of biharmonic maps with potential, in the particular case represented by conformal maps between equidimensional manifolds. Some examples are constructed in particular cases (Euclidean space and sphere).

From Conic to Cylindrical Map Projections

open access: yesGeodetski Vestnik, 2023
In books and textbooks on map projections, cylindrical, conic and azimuthal projections are usually considered separately. It is sometimes mentioned that cylindrical and azimuthal projections can be interpreted as limiting cases of conic, but this is ...

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.

Magnetopause as conformal mapping

open access: yesAnnales Geophysicae, 2022
Abstract. 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 expression of the magnetopause opens the door to properly map the magnetopause and ...
