Nonlinear Neumann problems on bounded Lipschitz domains
Electronic journal of differential equations, Tome 2005 (2005)
We prove existence and uniqueness, up to a constant, of an entropy solution to the nonlinear and non homogeneous Neumann problem

$\displaylines{ -\mathop{\rm div}[ \mathbf{a}(.,\nabla u)] +\beta (u)=f \quad\hbox{ in } \Omega \cr \frac{\partial u}{\partial \nu _{\mathbf{a}}}+\gamma (\tau u)=g \quad \hbox{on } \partial \Omega\,. }$

Our approach is based essentially on the theory of m-accretive operators in Banach spaces, and in order preserving properties.
