Existence of solutions for a fourth order problem at resonance

open access: yes, 2014
: In this work, we are interested at the existence of nontrivial solutions of two fourth order problems governed by the weighted p-biharmonic operator. The first is the following where λ 1 is the first eigenvalue for the eigenvalue problem ∆(ρ|∆u| p−2 ∆u)

Sign-changing Solutions for Fourth Order Elliptic Equation with Concave-convex Nonlinearities

open access: yes
In this paper, we study the following fourth order elliptic equation: Δ²u - Δu + V(x)u = κ(x)|u|q-2u + |u|p-2u in RN, where Δ² := Δ(Δ) is the biharmonic operator, 4 > N, 1 < q < 2 < p < 2* := 2N / (N - 4).
