Positivity of the infimum eigenvalue for equations of p(x)-Laplace type in RN

open access: yesBoundary Value Problems, 2013
We study the following elliptic equations with variable exponents −div(ϕ(x,|∇u|)∇u)=λf(x,u)in RN. Under suitable conditions on ϕ and f, we show the existence of positivity of the infimum of all eigenvalues for the problem above, and then give an ...

Sharp estimates on the first Dirichlet eigenvalue of nonlinear elliptic operators via maximum principle

open access: yesAdvances in Nonlinear Analysis, 2018
In this paper, we study optimal lower and upper bounds for functionals involving the first Dirichlet eigenvalue λF⁢(p,Ω){\lambda_{F}(p,\Omega)} of the anisotropic p-Laplacian ...

Existence of an unbounded branch of the set of solutions for equations of p(x)-Laplace type

open access: yesBoundary Value Problems, 2014
We are concerned with the following nonlinear problem −div(ϕ(x,|∇u|)∇u)=μ|u|p(x)−2u+f(λ,x,u,∇u)in Ω subject to Dirichlet boundary conditions, provided that μ is not an eigenvalue of the p(x)-Laplacian.

A multiplicity result for the scalar field equation

open access: yesAdvances in Nonlinear Analysis, 2014
We prove the existence of N - 1 distinct pairs of nontrivial solutions of the scalar field equation in ℝN under a slow decay condition on the potential near infinity, without any symmetry assumptions.

Multiplicity of solutions to discrete inclusions with the p(k)-Laplace type equations

open access: yesNonautonomous Dynamical Systems, 2018
In this article, we prove the existence and multiplicity of solutions to discrete inclusions with the p(k)-Laplace type equations. We are interested in the existence of three solutions with the aid of linking arguments and using a three critical points ...

Optimal Design Problems for the First p-Fractional Eigenvalue with Mixed Boundary Conditions

open access: yesAdvanced Nonlinear Studies, 2018
In this paper, we study an optimal shape design problem for the first eigenvalue of the fractional p-Laplacian with mixed boundary conditions. The optimization variable is the set where the Dirichlet condition is imposed (that is restricted to have ...

Weak homoclinic solutions to discrete nonlinear problems of Kirchhoff type with variable exponents

open access: yes, 2017
In this paper, we prove the existence of weak homoclinic solutions for discrete nonlinear problems of Kirchhoff type. The proof of the main result is based on a minimization method. As extension, we prove the existence result of weak homoclinic solutions

Estimates for the first eigenvalue for p-Laplacian with mixed boundary conditions

open access: yes, 2018
In this article, we consider eigenvalue problems on domains with an interior hole. Precisely, we show a Cheng-type inequality on manifolds, and certain Faber-Krahn inequalities on space forms.
