摘要：
In this paper we study existence and uniqueness of solutions to Dirichlet problems as {g(u) - div (Du/root 1 + |Du|(2 )= f in Omega, u = 0 on partial derivative Omega, where Omega is an open bounded subset of R-N(N >= 2) with Lipschitz boundary, g : R -> R is a continuous function and f belongs to some Lebesgue space. In particular, under suitable saturation and sign assumptions, we explore the regularizing effect given by the absorption term g(u) in order to get solutions for data f merely belonging to L-1(Omega) and with no small-ness assumptions on the norm. We also prove a sharp boundedness result for data in L-N(Omega) as well as uniqueness if g is increasing.
