An Application of Variational Minimization: Quasi-Harmonic Coons Patches

open access: yesJournal of Function Spaces, 2022
For a minimal surface, the mean curvature of the surface vanishes for all possible parameterizations which results in a second-order nonlinear partial differential equation (pde), whose solution in general is the desired surface as the unknown function ...

A Level Set-Based Model for Image Segmentation under Geometric Constraints and Data Approximation

open access: yesJournal of Imaging, 2023
In this paper, we propose a new model for image segmentation under geometric constraints. We define the geometric constraints and we give a minimization problem leading to a variational equation.

D-type minimal conformal matter: quantum curves, elliptic Garnier systems, and the 5d descendants

open access: yesJournal of High Energy Physics, 2023
We study the quantization of the 6d Seiberg-Witten curve for D-type minimal conformal matter theories compactified on a two-torus. The quantized 6d curve turns out to be a difference equation established via introducing codimension two and four surface ...

Significance of haphazard motion and thermal migration of alumina and copper nanoparticles across the dynamics of water and ethylene glycol on a convectively heated surface

open access: yesCase Studies in Thermal Engineering, 2021
Sequel to all the published facts on the dynamics of water and ethylene glycol on a convectively heated surface conveying alumina and copper nanoparticles as applicable in engineering and industry, noting is known on the significance of haphazard motion ...

Wilson Loops and Minimal Surfaces [PDF]

open access: yes, 1999
The AdS/CFT correspondence suggests that the Wilson loop of the large N gauge theory with N=4 supersymmetry in 4 dimensions is described by a minimal surface in AdS_5 x S^5. We examine various aspects of this proposal, comparing gauge theory expectations

Minimal Lagrangian surfaces in CH^2 and representations of surface groups into SU(2,1) [PDF]

open access: yes, 2012
We use an elliptic differential equation of Tzitzeica type to construct a minimal Lagrangian surface in the complex hyperbolic plane CH^2 from the data of a compact hyperbolic Riemann surface and a small holomorphic cubic differential.

The Weierstrass-Enneper Representation using hodographic coordinates on a minimal surface [PDF]

open access: yes, 2003
In this paper we obtain the general solution to the minimal surface equation, namely its local Weierstrass-Enneper representation, by using a system of hodographic coordinates.
