Multiple positive solutions for Schrödinger-Poisson systems involving concave-convex nonlinearities

open access: yesElectronic Journal of Differential Equations, 2019
Summary: In this article, we study the existence of multiple positive solutions for Schrödinger-Poisson systems involving concave-convex nonlinearities and sign-changing weight potentials. With the help of Nehari manifold and Ljusternik-Schnirelmann category theory, we investigate how the coefficient \(g(x)\) of the critical nonlinearity affects the ...

Variational and numerical aspects of a system of ODEs with concave-convex nonlinearities

open access: yesElectronic Journal of Differential Equations
We study a Hamiltonian system of ordinary differential equations under Dirichlet boundary conditions. The system features a mixed (concave-convex) power nonlinearity with a positive parameter $\lambda$. We show multiplicity of nonnegative solutions for a
