Abstract
The existence of a positive and a negative solution of a problem of the type - Deltau + f(x, u, delu) = 0 in Q. u = 0 on deltaOmega is proved, when f has a growth at infinity depending both on u and on delu. The techniques are based on an iterative scheme of Mountain Pass "approximated" solutions and the use of a suitable truncature method. (C) 2004 Elsevier Ltd.
