Solution of inverse nodal problems

Inverse Problems, 1989
We show that the coefficients in a second-order differential equation can be determined from the positions of the nodes for the eigenfunctions. We prove uniqueness results, derive approximate solutions, give error bounds and present numerical experiments.

Nodal Solutions for Indefinite Robin Problems

Bulletin of the Malaysian Mathematical Sciences Society, 2017
Given a bounded domain \(\Omega \subseteq \mathbb{R}^N\) with a \(C^2\)-boundary, the authors study semilinear Robin problems of the form \[ \begin{cases} -\Delta u(z)+\xi(z)u(z) = f(z,u(z)) &\text{in }\Omega,\\ \frac{\partial u}{\partial n}+\beta(z)u=0 &\text{on }\partial \Omega, \end{cases} \] where the potential function \(\xi\) belongs to \(L^s ...

Nodal solutions of -Laplacian equations

Nonlinear Analysis: Theory, Methods & Applications, 2007
The aim of this paper is to study the existence of nodal radial solutions for the \(p(x)\)-Laplacian equation of the form \[ \begin{gathered} -\text{div}(|\nabla |^{p(x)-2}\nabla u)+ a(x)|u|^{p(x)-2} u=|u|^{q(x)- 2} u\quad\text{in }\Omega,\\ u\in W^{1,p(x)}_0(\Omega).\end{gathered}\tag{1} \] Using a variational method, the authors prove that, for any ...

Nodal solutions of a p-Laplacian equation

Proceedings of the London Mathematical Society, 2005
Summary: We prove that the \(p\)-Laplacian problem \(-\Delta_p u = f(x, u)\), with \(u \in W_0^{1,p}(\Omega)\) on a bounded domain \(\Omega \subset \mathbb R^N\), with \(p > 1\) arbitrary, has a nodal solution provided that \(f : \Omega\times\mathbb R \to \mathbb R\) is subcritical, and \(f(x, t) / |t|^{p-2}\) is superlinear.

Multiple nodal solutions for elliptic equations

Nonlinear Analysis: Theory, Methods & Applications, 2004
In the present study the authors obtain multiple sign-changing solutions for nonlinear elliptic equations under weaker conditions (without assuming that the corresponding functional is \(C^2)\), and multiple critical points for invariant functional under group actions.
