Multiple positive solutions for superlinear Kirchhoff type problems on R^N

Electronic Journal of Differential Equations, 2015
By using critical point theory, we establish the existence of infinitely many weak solutions for a class of Navier boundary-value problem depending on two parameters and involving the p(x)-biharmonic operator.

Ground state solutions for elliptic Kirchhoff–Boussinesq type problems with supercritical exponential growth

Boundary Value Problems
In this work, we are interested in studying the existence of a ground state solution for the problem Δ ( w β ( x ) Δ u ) ± div ( w β ( x ) | ∇ u | p − 2 ∇ u ) = f ( x , u )  in  B , and u = ∂ u ∂ ν = 0 on ∂ B , $$ \Delta (w_{\beta}(x)\Delta u ) \pm \text{

Domain Perturbations of the Biharmonic Operator

, 1965
Eigenvalue problems for the biharmonic operator (iterated Laplacian)L= ΔΔ will be studied on bounded plane domains. Our purpose is to obtain asymptotic variational formulae for eigenvalues and eigenfunctions under the deformation of removing an ∊-disk ...

On a p(x)-Biharmonic Kirchhoff Problem with Logarithmic Nonlinearity

Mathematics
This paper is devoted to the study of a class of the p(x)-biharmonic Kirchhoff problem with logarithmic nonlinearity. With the help of the mountain pass theorem, the existence of a nontrivial weak solution to this problem is obtained.
