Multiplicity of negative-energy solutions for singular-superlinear Schrödinger equations with indefinite-sign potential
Carlos Alberto Santos, Ricardo Alves Lima, Kaye Silva
We are concerned with the multiplicity of positive solutions for the singular superlinear and subcritical Schrödinger equation $$ \begin{array}{c} -Δu +V(x)u=λa(x)u^{-γ}+b(x)u^{p}~…

The bifurcation diagram of an elliptic Kirchhoff-type equation with respect to the stiffness of the material
Kaye Silva
We study a superlinear and subcritical Kirchhoff type equation which is variational and depends upon a real parameter . The nonlocal term forces some of the fiber maps associate…

The fibering method approach for a non-linear Schrödinger equation coupled with the electromagnetic field
Gaetano Siciliano, Kaye Silva
We study, with respect to the parameter , the following Schrödinger-Bopp-Podolsky system in \begin{equation*} \left\{ \begin{aligned} -&Δu+ωu+q^2ϕu=|u|^{p-2…
