Three Weak Solutions for a Critical Non-Local Problem with Strong Singularity in High Dimension
Autor: Gabriel Neves Cunha, Francesca Faraci, Kaye Silva
Publikováno v: Mathematics, Vol 12, Iss 18, p 2910 (2024)
In this paper, we deal with a strongly singular problem involving a non-local operator, a critical nonlinearity, and a subcritical perturbation. We apply techniques from non-smooth analysis to the energy functional, in combination with the study of t

Multiplicity of positive solutions for a gradient type cooperative/competitive elliptic system
Autor: Kaye Silva, Steffanio Moreno Sousa
Publikováno v: Electronic Journal of Differential Equations, Vol 2020, Iss 10,, Pp 1-14 (2020)
We study the existence of positive solutions for gradient type cooperative, competitive elliptic systems, which depends on real parameters $\lambda,\mu$. Our analysis is purely variational and depends on finer estimates with respect to the Nehari

Extremal parameter for double phase problem with concave-convex nonlinearity
Autor: Pawan Kumar Mishra, Kaye Silva, Vinayak Mani Tripathi
Note: Please see pdf for full abstract with equations. In this work, we study the following problem −Δpu − div(μ(x)|∇u|q−2∇u) = λf(x)|u|γ−2u + g(x)|u|r−2u in Ω, u = 0 on ∂Ω, where Ω ⊂ RN,N ≥ max{2, p} is a bounded smooth do

On the extreme value of the Nehari manifold method for a class of Schrödinger equations with indefinite weight functions
Autor: Kaye Silva, José Carlos de Albuquerque
Publikováno v: Journal of Differential Equations. 269:5680-5700
In this work we are concerned with the following class of equations − Δ p u − λ h ( x ) | u | p − 2 u = f ( x ) | u | γ − 2 u , in R N , involving indefinite weight functions. The existence of solution may depend on the parameter λ. We an

Multiplicity of negative-energy solutions for singular-superlinear Schrödinger equations with indefinite-sign potential
Autor: Kaye Silva, Ricardo Lima Alves, Carlos Alberto Santos
Publikováno v: Communications in Contemporary Mathematics. 24
We are concerned with the multiplicity of positive solutions for the singular superlinear and subcritical Schrödinger equation [Formula: see text] beyond the Nehari extremal value, as defined in [Y. Il’yasov, On extreme values of Nehari manifold v

On the Brezis–Nirenberg problem for a Kirchhoff type equation in high dimension
Autor: Francesca Faraci, Kaye Silva
Publikováno v: Calculus of Variations and Partial Differential Equations. 60
The present paper deals with a parametrized Kirchhoff type problem involving a critical nonlinearity in high dimension. Existence, non existence and multiplicity of solutions are obtained under the effect of a subcritical perturbation by combining va

Finer analysis of the Nehari set associated to a class of Kirchhoff-type equations
Autor: Steffânio Moreno de Sousa, Kaye Silva
Publikováno v: SN Partial Differential Equations and Applications. 1
We extend and improve the results of Chen-Ou (Comput. Math. Appl. 77(10):2859–2866, 2019), which concern a Kirchhoff-type equation depending on two real parameters $$\lambda ,\mu$$ . Our technique, which relies upon a refined analysis of the Nehari
