Global bifurcation result for the p-biharmonic operator

We prove isolatedness and simplicity of the first eigenvalue for the p-biharmonic operator. We also prove that the first eigenvalue is a bifurcation point for associated nonlinear boundary value problem....

Global bifurcation result for the p-biharmonic operator

We prove that the nonlinear eigenvalue problem for the p-biharmonic operator has positive prinicpal eigenvalue which is simple and isolated. The corresponding eigenfunction is positive. We also prove that the principle eigenvalue is...

Estimates of the principal eigenvalue of the p-biharmonic operator

We provide estimates from below and from above for the principal eigenvalue of the p-biharmonic operator on a bounded domain with the Navier boundary conditions. We apply these estimates to study the asymptotic behavior of the princ...

Continuous dependence of eigenvalues of p-biharmonic problems on p

We are concerned with the Dirichlet and Neumann eigenvalue problem for ordinary quasilinear fourth-order (p-biharmonic) equation. We prove that the eigenvalues depend continuously on p, and that they interlace with the eigenvalues of the Nav...

Asymptotics for the principal eigenvalue of the p-biharmonic operator on the ball as p approaches 1

Using the estimates of the principal eigenvalue of the p-biharmonic operator on the ball from below and from above, we provide its asymptotic analysis as p approaches 1....

Estimates of the Principal Eigenvalue of the p-Laplacian and the p-Biharmonic Operator

We survey recent results concerning estimates of the principal eigenvalue of the Dirichlet p-Laplacian and the Navier p-biharmonic operator on a ball of radius $R$ in $R^N$ and its asymptotics for p approaching 1 and infinity....

Pseudomodes for Biharmonic Operators with Complex Potentials

This article is devoted to the construction of pseudomodes of one-dimensional biharmonic operators with complex-valued potentials via the WKB method. As a by-product, the shape of pseudospectrum near infinity can be described. This ...

Global bifurcation result for Dirichlet and Neumann p-biharmonic problem

We consider the Dirichlet and Neumann fourth-order quasilinear boundary value problem for the so-called p-biharmonic equation. We determine the Leray-Schauder degree of the associated operators. As a standard consequence, we then pr...

Existence of two non-zero weak solutions for a p(•)-biharmonic problem with Navier boundary conditions

In this paper, the existence of non-trivial weak solutions for some problems with Navier boundary conditions driven by the p(center dot)-biharmonic operator is investigated. The proofs combine variational methods with topological ar...
