Abstract

In this paper, we consider the H\'enon problem in the setting of Orlicz-Sobolev spaces: \begin{equation*} \begin{cases} -\Delta_g u= |x|^\alpha h( u) \quad \text{in }B\\ u>0 \quad \text{in }B\\ u= 0 \quad \text{on }\partial B\\ \end{cases} \end{equation*}where BB is the unit ball in Rn\mathbb{R}^n, g=Gg=G', h=Hh=H' are N-functions and the operator Δg-\Delta_g is the gg-Laplacian. We show that the symmetric term xα|x|^\alpha, for α>0\alpha>0, allows to have radial solutions even for supercritical HH, generalizing results for the classical H\'enon equation. We also show that radial solutions are indeed bounded. Finally, we state a Pohozaev's identity in Orlicz-Sobolev spaces that we apply to get a range in α\alpha for which the problem has no bounded solutions.
