Abstract

In this paper we consider a class of nonlinear elliptic problems of the type

$$ \left\{ \begin{gathered} - div(a(x,\nabla u)) - div(\Phi (x,u)) = fin\Omega \hfill \\ u = 0on\partial \Omega , \hfill \\ \end{gathered} \right. $$

where Ω is a bounded open subset of R N, N ≥ 2, f is a L 1 (Ω) function or a Radon measure with bounded total variation. We fix some structural conditions on a and Φ to prove uniqueness results when fL 1 (Ω).
