Critical points with prescribed energy for a class of functionals depending on a parameter: existence, multiplicity and bifurcation results
Humberto Ramos Quoirin, Gaetano Siciliano, Kaye Silva
We look for critical points with prescribed energy for the family of even functionals , where are functionals on a Banach space , and $μ\in \mathbb…
Ground states of elliptic problems over cones
Giovany M. Figueiredo, Humberto Ramos Quoirin, Kaye Silva
Given a reflexive Banach space , we consider a class of functionals that do not behave in a uniform way, in the sense that the map , , do…
On the structure of the Nehari set associated to a Schrödinger-Poisson system with prescribed mass: old and new results
Gaetano Siciliano, Kaye Silva
In this paper we apply the fibering method of Pohozaev to a Schrödinger-Poisson system, with prescribed norm of the unknown, in the whole . The method makes…
On the extreme value of the Nehari manifold method for a class of Schrödinger equations with indefinite weight functions
José Carlos de Albuquerque, Kaye Silva
In this work we are concerned with the following class of equations \[ -Δ_p u -λh(x)|u|^{p-2}u=f(x)|u|^{γ-2}u, \quad \mbox{in } \mathbb{R}^N, \] involving indefinite weight functio…
On an abstract bifurcation result concerning homogeneous potential operators with applications to PDEs
Kaye Silva
We study an abstract equation in a reflexive Banach space, depending on a real parameter . The equation is composed by homogeneous potential operators. By analyzing the Nehari s…
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}~…
