Radial symmetry of positive solutions to nonlinear polyharmonic Dirichlet problems

Journal für die reine und angewandte Mathematik (Crelles Journal), 2008
The authors consider the semilinear polyharmonic Dirichlet problem \[ \begin{aligned} (-\Delta)^m u= f(u)\quad &\text{in }B,\\ u= {\partial u\over\partial r}=\cdots= {\partial^{m-1} u\over\partial r^{m-1}}= 0\quad &\text{on }\partial B.\end{aligned} \] Here \(B\) is the unit ball in \(\mathbb{R}^n\), \(r= |x|\) is the radial variable and \(f: [0,\infty)

Existence of positive radial solutions for the n-dimensional p-Laplacian

Nonlinear Analysis: Theory, Methods & Applications, 2001
The authors study the following Dirichlet problem on the unit ball \(B_1\) centered at the origin of \(\mathbb{R}^n\): \[ -\Delta_p u=q(|x|)f(u), \quad x\in B_1, \qquad u(x)=0, \quad x\in\partial B_1, \] where the functions \(q:(0,1)\to \mathbb{R}_+\) and \(f:\mathbb{R}\to \mathbb{R}\) are continuous, and \(\Delta_p\), \(p>1\), denotes the \(p ...

Positive Radial Solutions of Some Nonlinear Partial Differential Equations

Mathematische Nachrichten, 1997
AbstractWe consider Dirichlet boundary value problems for a class of nonlinear ordinary differential equations motivated by the study of radial solutions of equations which are perturbations of the p‐Laplacian.
