چکیده

Let $\Omega$ be a bounded open subset of $\mathbb{R}^{N},$ $N\geq 2$. In this paper we give an existence result of bounded solution, in Musielak spaces, for unilateral problems associated to the nonlinear elliptic equation $$-\mathop{\rm div}a(x,u,{\nabla}u)+g(x,u,\nabla u)=f \quad\text{in }{\Omega},$$ where the nonlinearity $g$ does not satisfy the well known sign condition and $f$ is an integrable source.
