Abstract
In this paper we study the existence of solutions of the Dirichlet problem associated to the following nonlinear PDE
In this paper we study the existence of solutions of the Dirichlet problem associated to the following nonlinear PDE \begin{document}$ \begin{equation*} { } -{{{\rm{\;div}}}}\big(a(x)\,\nabla u|\nabla u|^{p-2}\big) -{{{\rm{\;div}}}}\big( |u|^{(r-1)\lambda+1}\nabla u|\nabla u|^{\lambda-2}\big) = f \end{equation*} $\end{document} where $ 1 < \lambda \leq p $, $ r > 1 $ and $ f \in L^1(\Omega) $.
