Abstract:

This paper is devoted to the study of biharmonic problems. More precisely, we consider the following inhomogeneous problem

{            (    )    ( |u|2∗(s)−2u)      (      )
   Δ2u  −  μ   |xu|4- =    ---|x|s---  +  λ   |xu|4−α-  + f (x ),  x ∈  Ω,

   u =  ∂∂un-=  0,                                              x ∈  ∂ Ω,

where Ω is a bounded domain in N and N 5, under sufficient conditions on the data and the considered parameters, we prove the existence and multiplicity of solutions, by virtue of Ekeland’s Variational Principle and the Mountain Pass Lemma.
