Radial Positive Solutions for p-Laplacian Supercritical Neumann Problems [PDF]

open access: greenBruno Pini Mathematical Analysis Seminar, 2017
This paper deals with existence and multiplicity of positive solutions for a quasilinear problem with Neumann boundary conditions. The problem is set in a ball and admits at least one constant non-zero solution; moreover, it involves a nonlinearity that ...

Existence of positive radial solutions of general quasilinear elliptic systems [PDF]

open access: goldAdvances in Nonlinear Analysis
Let Ω⊂Rn(n≥2)\Omega \subset {{\mathbb{R}}}^{n}\hspace{0.33em}\left(n\ge 2) be either an open ball BR{B}_{R} centred at the origin or the whole space. We study the existence of positive, radial solutions of quasilinear elliptic systems of the form Δpu=f1(∣

Positive radial solutions for Dirichlet problems in the ball

open access: hybridNonlinear Analysis, 2023
We are concerned with existence, localization and multiplicity of positive radial solutions to Dirichlet problems with Ø-Laplacians in a ball, in both scalar and system cases. Our approach essentially relies on fixed point index computations and a main feature is that it avoids any Harnack type inequality.

On Positive Radial Solutions for a Class of Elliptic Equations [PDF]

open access: yesThe Scientific World Journal, 2014
A class of elliptic boundary value problem in an exterior domain is considered under some conditions concerning the first eigenvalue of the relevant linear operator, where the variables of nonlinear term fs,u need not to be separated.

Radial positive solutions for a nonpositone problem in an annulus

open access: greenElectronic Journal of Differential Equations, 2014
The main purpose of this article is to prove the existence of radial positive solutions for a nonpositone problem in an annulus when the nonlinearity is superlinear and has more than one zero.

Multiplicity Results of Positive Radial Solutions for p-Laplacian Problems in Exterior Domains [PDF]

open access: goldBoundary Value Problems, 2008
We find the second positive radial solution for the following p-Laplacian problem: div(|∇u|p−2∇u)+K(|x|)uq=0 in Ω, u|∂Ω=0, u(x)→μ>0 as |x|→∞, where Ω={x∈ℝN:|x|>r0}, r0>0, N>p>1, K∈C(Ω,(0,à ...

Asymptotic behavior of positive radial solutions to elliptic equations approaching critical growth

open access: diamondElectronic Journal of Differential Equations, 2020
We study the asymptotic behavior of radially symmetric solutions to the subcritical semilinear elliptic problem $$\displaylines{ -\Delta u = u^{\frac{N+2}{N-2}}/[\log(e+u)]^{\alpha}\quad \text{in } \Omega=B_R(0)\subset\mathbb{R}^N,\cr u>0,\quad ...
