Existence of positive radial solutions for a semilinear elliptic system without variational structure

, 2007
International audienceIn this article we consider (component-wise) positive radial solutions of a weakly coupled semilinear elliptic system in a ball with homogeneous Dirichlet data. We deal with a nonvariational problem.

Existence of positive solutions for p(x)-Laplacian problems

Electronic Journal of Differential Equations, 2007
We consider the system of differential equations $$displaylines{ -Delta_{p(x)} u=lambda [g(x)a(u) + f(v)] quadhbox{in }Omegacr -Delta_{q(x)} v=lambda [g(x)b(v) + h(u)] quadhbox{in }Omegacr u=v= 0 quadhox{on } partial Omega }$$ where $p(x) in C ...

Existence and multiplicity of positive radial solutions to nonlocal boundary-value problems in exterior domains

Electronic Journal of Differential Equations, 2016
In this article, we consider nonlocal p-Laplacian boundary-value problems with integral boundary conditions and a non-negative real-valued boundary condition as a parameter.

Positivity and nonexistence of solutions for quasilinear inequalities

Electronic Journal of Differential Equations, 2016
We prove a positivity property and a nonexistence theorem for weak solutions of quasilinear differential equalities in R^N. To obtain our results, we use a comparison principle.
