Positive radial solutions for and related topics

Applicable Analysis, 1990
We study the existence of positive radial solutions of semilinear elliptic equations . By using a variational method and finite balls approach, we prove that there exists a positive radial solution with finite energy on provided that K satisfies the following conditions (i) for small r > 0, β > 0 and α∊(0,n), (ii) K(r) ≥ 0 for large r and and (iii ...

Positive radial solutions for a quasilinear system

Applicable Analysis, 2006
In this article, general existence theorems are presented for a quasilinear system We obtain some existence theorems by a simple application of the Schauder fixed-point theorem and degree theory. We do not require conditions of the nonlinearity f, g at zero or at infinity, and we do not need upper bounds for p, q involving the dimension n. We study the

On the existence of positive radial solutions for a certain class of elliptic BVPs

Journal of Mathematical Analysis and Applications, 2004
The aim of this paper is to answer the question, when a certain BVP of elliptic type possesses positive radial solutions. We develop duality and variational principles for this problem.

Positive radial solutions for a class of (p, q) Laplacian in a ball

Positivity, 2022
The authors are concerned with the Dirichlet problem \[ \begin{cases} -\Delta_pu-\Delta_qu=\lambda f(u) \text{ in }\Omega, \\ u=0 \text{ on }\Omega, \end{cases} \] where \(\Delta_ru=\operatorname{div}(\vert\nabla u\vert^{r-2}\nabla u)\) is the \(p\)-Laplacian, \(\Omega\) is the unit open ball, and \(p>q>1\).
