Positive solutions for the Neumann p-Laplacian

Monatshefte für Mathematik, 2017
Let \(\Omega\subset {\mathbb R}^N\) be a bounded domain with smooth boundary. This paper is devoted to the refined qualitative analysis of positive solutions of the quasilinear elliptic problem \[ -\Delta_pu+\lambda u^{p-1}=f(x,u)\quad\text{in}\Omega, \] subject to the Neumann boundary condition \(\frac{\partial u}{\partial n}=0\) on \(\partial\Omega\).

Multiple solutions of positively homogeneous equations

Nonlinear Analysis: Theory, Methods & Applications, 2002
The authors study the existence and multiplicity of periodic solutions to the following system \[ u''- Au + \mu u^+ - \nu u^- = v + h(t), \] where \(h\) is a continuous and \(T\)-periodic function, \(v\in \mathbb{R}^N\), and \(A\) is a symmetric matrix. The main results are the following: (1) Under some reasonable assumptions, this system has at least \

Uniqueness of Positive Solutions of Elliptic Problems

Bulletin of the London Mathematical Society, 1984
Soit Ω un domaine borne d'un espace euclidien E n . On considere le probleme aux valeurs limites formel: Lu=-Σ i,j=1 n D i (A ij D j u)+p(x,u)u=0 dans Ω; u=0 sur ∂Ω.

Positive Solution of Lighthill-Type Equations

Zeitschrift für Analysis und ihre Anwendungen, 2018
We study a unique solvability of Volterra integral equations of Lighthill’s type subject to a positive solution on [0,\infty) . Also the asymptotics of the solution at the infinity is examined.

Positive Solutions of Quasilinear Elliptic Equations

Mathematical Notes, 2005
The author studies the existence of radially symmetric solutions of the problem \[ -\Delta_p \varphi = \lambda\varphi^q - | \nabla\varphi| ^s \quad\text{in}\quad B, \qquad \varphi > 0 \quad\text{in}\quad B, \qquad \varphi = 0 \quad\text{on}\quad \partial B, \tag \(*\) \] where \(\Delta_p\varphi = \text{div}(| \nabla\varphi| ^{p-2}\nabla\varphi)\), \(p ...
