Prescribed energy solutions of concave-convex type problems involving sign-changing or vanishing weights

Kanishka Perera, Humberto Ramos Quoirin, Kaye Silva

We provide an abstract approach to find couples $(I^», u) \in R \times X$ satisfying $$Î¦_Î»(u)=c \quad \mbox{and} \quad Î¦'_Î»(u)=0,$$ for some suitable values of $c \in \m…

Further applications of the Nehari manifold method to functionals in $C^{1} (X ∖ {0})$

Edir J. F. Leite, Humberto Ramos Quoirin, Kaye Silva

We proceed with the study of the Nehari manifold method for functionals in $C^{1} (X ∖ {0})$ , where $X$ is a Banach space. We deal now with functionals whose fibering maps h…
