Abstract : In the present paper we prove existence results for solutions to nonlinear elliptic Neumann problems whose prototype is \begin{equation*} \begin{cases} -\Delta {p} u -\text{div} cx|u|^{p-2}u =f & \text{in}\ \Omega, \\ \left | abla u|^{p-2} abla u+ cx|u|^{p-2}u ight\cdot\underline n=0 & \text{on}\ \partial \Omega \,, \end{cases} \end{equation*} when $f$ is just a summable function. Our approach allows also to deduce a stability result for renormalized solutions and an existence result for operator with a zero order term.

Keywords : Nonlinear elliptic equations Neumann problems renormalized solutions existence results
