Ground state solutions for weighted biharmonic problem involving non linear exponential growth

Abstract

In this article, we study the following problem $$Δ(w(x)Δu) = \ f(x,u) \quad\mbox{ in }\quad B, \quad u=\frac{\partial u}{\partial n}=0 \quad\mbox{ on } \quad\partial B,$$ where $B$ is the unit ball of ${\mathbb{R}}^4$ and $w(x)$ a singular weight of logarithm type. The reaction source $f(x,u)$ is a radial function with respect to $x$ and it is critical in view of exponential inequality of Adams' type. The existence result is proved by using the constrained minimization in Nehari set coupled with the quantitative deformation lemma and degree theory results.
