Some applications of the Nehari manifold method to functionals in
Edir Junior Ferreira Leite, Humberto Ramos Quoirin, Kaye Silva
Given a real Banach space , we show that the Nehari manifold method can be applied to functionals which are in . In particular we deal with functionals…
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…
Some uniqueness results in quasilinear subhomogeneous problems
Humberto Ramos Quoirin
We establish uniqueness results for quasilinear elliptic problems through the criterion recently provided in \cite{DFMST}. We apply it to generalized -Laplacian subhomogeneous p…
Uniqueness and positivity issues in a quasilinear indefinite problem
Uriel Kaufmann, Humberto Ramos Quoirin, Kenichiro Umezu
We consider the problem $$ (P_λ)\quad -Δ_{p}u=λu^{p-1}+a(x)u^{q-1},\quad u\geq0\quad\mbox{ in }Ω$$ under Dirichlet or Neumann boundary conditions. Here is a smooth bounded doma…
Nonnegative solutions of an indefinite sublinear Robin problem II: local and global exactness results
Uriel Kaufmann, Humberto Ramos Quoirin, Kenichiro Umezu
We go further in the investigation of the Robin problem : in , in , on ; on a bounded domain $Ω\subset\mathbb{R}^…
