Abstract. In this article, we prove the existence of entropy solutions for the Dirichlet problem
$-div[{\mathcal{A}}(x,\nabla u){\omega}_1 +{\mathcal{B}}(x,u,\nabla u){\omega}_2] = f(x), in\ \Omega,$
$u(x) = 0, on\ \partial\Omega,$
where $\Omega$ is a bounded open set of $\mathbb{R}^N$ , $N\geq 2$ and $f\in L^1(\Omega)$ . An example is provided to support our result.
