A New Minimax Theorem for a Class of -Functionals
Denilson S. Pereira, João R. Santos Júnior, João F. F. Silva
We establish a new abstract minimax theorem for obtaining ground-state critical points of a class of \(C^{1}\)-functionals. The central feature of this class is that the associated…
Existence of multi-bump solutions to biharmonic operator with critical exponential growth in
Alânnio B. Nóbrega, Denilson S. Pereira
Using variational methods, we establish existence of multi-bump solutions for the following class of problems $$ \left\{ \begin{array}{l} Δ^2 u +(λV(x)+1)u = f(u), \quad \mbox{in}…
Infinitely many sign-changing solutions for a class of elliptic problem with exponential critical growth
Denilson Pereira
In this work we prove the existence of infinitely many nonradial solutions that change signal to the problem in with on , where is the unit bal…
Multiplicity of multi-bump type nodal solutions for a class of elliptic problems with exponential critical growth in
Claudianor O. Alves, Denilson S. Pereira
In this paper, we establish the existence and multiplicity of multi-bump nodal solutions for the following class of problems $$ -Δu+(λV(x)+1)u=f(u),~~\mbox{in}~~\mathbb{R}^2, $$ wh…
Existence and nonexistence of least energy nodal solution for a class of elliptic problem in
Claudianor O. Alves, Denilson S. Pereira
In this work, we prove the existence of least energy nodal solution for a class of elliptic problem in both cases, bounded and unbounded domain, when the nonlinearity has exponenti…
