Abstract
In this paper, we are interested in the existence result of solutions for nonlinear and singular Dirichlet problem whose model is
where \(\Omega \) is a bounded open subset of \(\mathbb {R}^N (N\ge 2)\), b(s) is a positive continuous function which blows up for a finite value of the unknown, \(\mu (x)\) is positive, bounded and measurable, \(0<\theta < 1\), and the source f belongs to \(L^1(\Omega )\).
