THE ROBIN PROBLEM FOR THE HÉNON EQUATION [PDF]
Bulletin of the Australian Mathematical Society, 2013 AbstractIn this paper, we consider the following Robin problem:$$\begin{eqnarray*}\displaystyle \left\{ \begin{array}{ @{}ll@{}} \displaystyle - \Delta u= \mid x{\mathop{\mid }\nolimits }^{\alpha } {u}^{p} , \quad & \displaystyle x\in \Omega , \\ \displaystyle u\gt 0, \quad & \displaystyle x\in \Omega , \\ \displaystyle \displaystyle \frac ...

An inverse three spectra problem for Sturm–Liouville operators
Boundary Value Problems, 2018 In this paper, we consider the inverse three spectra problems of recovering the Sturm–Liouville equation by the spectra of the Neumann–Dirichlet boundary value problem on [0,1] $[0,1]$, the Neumann–Robin problem on [0,1/2] $[0,1/2]$, and the Robin ...

The spacewise dependent source identification problem for the elliptic-telegraph differential equation with involution and Robin condition [PDF]
E-Journal of Analysis and Applied Mathematics, 2023 In the present paper, the spacewise dependent source identification problem (SIP) for the elliptic-telegraph differential equation with involution and Robin condition is investigated. The theorem on stability estimates for the solution of this space-wise

Positive solutions for nonvariational Robin problems
Asymptotic Analysis, 2018 We study a nonlinear Robin problem driven by the p-Laplacian and with a reaction term depending on the gradient (convection term). Using the theory of nonlinear operators of monotone-type and the asymptotic analysis of a suitable perturbation of the original equation, we show the existence of a positive smooth solution.

Asymptotic analysis of Sturm-Liouville problem with Robin and two-point boundary conditions
Lietuvos Matematikos Rinkinys, 2022 We analyze the initial value problem and get asymptotic expansions for solution. We investigate the characteristic equation for Sturm-Liouville problem with one classical Robin type boundary condition and another two-point nonlocal boundary condition ...

A Rigidity Result for the Robin Torsion Problem
The Journal of Geometric Analysis, 2023 AbstractLet$$\Omega \subset \mathbb {R}^2$$Ω⊂R2be an open, bounded and Lipschitz set. We consider the torsion problem for the Laplace operator associated to$$\Omega $$Ωwith Robin boundary conditions. In this setting, we study the equality case in the Talenti-type comparison, proved in Alvino et al. (Commun Pure Appl Math 76:585–603, 2023)..

Entropy Solution for Doubly Nonlinear Elliptic Anisotropic Problems with Robin Boundary Conditions
International Journal of Differential Equations, 2015 We study in this paper nonlinear anisotropic problems with Robin boundary conditions. We prove, by using the technic of monotone operators in Banach spaces, the existence of a sequence of weak solutions of approximation problems associated with the ...

Mathematics, 2020 We study properties of generalized solutions of the Dirichlet–Robin problem for an elasticity system in the exterior of a compact, as well as the asymptotic behavior of solutions of this mixed problem at infinity, with the condition that the energy ...

The numerical solution of forward and inverse Robin problems for Laplace’s equation
Boundary Value Problems, 2019 The Robin boundary value problem for Laplace’s equation in the elliptic region (which is a forward problem) and its related inverse problem can be used to reconstruct Robin coefficients from measurements on a partial boundary (inverse problem).
