Necessary and sufficient conditions on the existence of solutions for the exterior Dirichlet problem of Hessian equations

open access: yesBoundary Value Problems, 2022
In this paper, we consider the exterior Dirichlet problem of Hessian equations σ k ( λ ( D 2 u ) ) = g ( x ) $\sigma _{k}(\lambda (D^{2}u))=g(x)$ with g being a perturbation of a general positive function at infinity. By estimating the eigenvalues of the

Asymptotic behavior of solutions of fully nonlinear equations over exterior domains

open access: yesComptes Rendus. Mathématique, 2021
In this paper, we consider the asymptotic behavior at infinity of solutions of a class of fully nonlinear elliptic equations $F(D^2u)=f(x)$ over exterior domains, where the Hessian matrix $(D^2u)$ tends to some symmetric positive definite matrix at ...

A Gradient Type Term for the k-Hessian Equation

open access: yesThe Journal of Geometric Analysis, 2023
In this paper, we propose a gradient type term for the $k$-Hessian equation that extends for $k>1$ the classical quadratic gradient term associated with the Laplace equation. We prove that such as gradient term is invariant by the Kazdan-Kramer change of variables.

The Dirichlet Problem of Hessian Equation in Exterior Domains

open access: yesMathematics, 2020
In this paper, we will obtain the existence of viscosity solutions to the exterior Dirichlet problem for Hessian equations with prescribed asymptotic behavior at infinity by the Perron’s method. This extends the Ju–Bao results on Monge–Ampère equations

Isogenies on twisted Hessian curves

open access: yesJournal of Mathematical Cryptology, 2021
Elliptic curves are typically defined by Weierstrass equations. Given a kernel, the well-known Vélu's formula shows how to explicitly write down an isogeny between Weierstrass curves. However, it is not clear how to do the same on other forms of elliptic

A projected Hessian Gauss-Newton algorithm for solving systems of nonlinear equations and inequalities

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Solving systems of nonlinear equations and inequalities is of critical importance in many engineering problems. In general, the existence of inequalities in the problem adds to its difficulty.

Noether symmetry approach in Eddington-inspired Born–Infeld gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
In this work, we take a short recap of a formal framework of the Eddington-inspired Born–Infeld (EiBI) theory of gravity and derive the point-like Lagrangian for underlying theory based on the use of Noether gauge symmetries (NGS).

Structural Fluctuation, Relaxation, and Folding of Protein: An Approach Based on the Combined Generalized Langevin and RISM/3D-RISM Theories

open access: yesMolecules, 2023
In 2012, Kim and Hirata derived two generalized Langevin equations (GLEs) for a biomolecule in water, one for the structural fluctuation of the biomolecule and the other for the density fluctuation of water, by projecting all the mechanical variables in ...
