Regularity and positivity of the solution

2017
In this section we show a regularity result1 that allows us to say that a nonnegative solution to (2.1.1) is bounded.

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 \(\partial\Omega\).

Positive solutions of sparse polynomial systems

Proceedings of the 45th International Symposium on Symbolic and Algebraic Computation, 2020
My lecture will survey some classical and recent lower and upper bounds for the number of positive solutions of systems of n sparse polynomial systems in n variables, including basic questions that are open. This is only a short summary of the talk.

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 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 ...
