Mohammed 1er, Oujda, Maroc) Omar Chakrone (Univ. Mohammed 1er, Oujda, Maroc) Mohammed Chehabi (Univ. Mohammed 1er, Oujda, Maroc) Abstract: In this paper, we study the existence of solutions to the following nonlinear elliptic problem in a bounded subset $\Omega$ of $\mathbb{R}^{N}$: $$\displaylines{ -\Delta _{p}u = f(x,u,\nabla u)+\mu \quad \hbox{in } \Omega ,\cr u = 0 \quad \hbox{on }\partial \Omega , }$$ where $\mu $ is a Radon measure on $\Omega $ which is zero on sets of $p$-capacity zero, $f:\Omega \times \mathbb{R}\times \mathbb{R} ^{N}\to \mathbb{R}$ is a Caratheodory function that satisfies certain conditions with respect to the one dimensional spectrum.
