Abstract

We present an algorithm to solve \lapuf(x,u)=g- \lap u - f(x,u) = g with Dirichlet boundary conditions in a bounded domain Ω\Omega. The nonlinearities are non-resonant and have finite spectral interaction: no eigenvalue of \lapD-\lap_D is an endpoint of 2f(Ω,\RR)ˉ\bar{\partial_2f(\Omega,\RR)}, which in turn only contains a finite number of eigenvalues. The algorithm is based in ideas used by Berger and Podolak to provide a geometric proof of the Ambrosetti-Prodi theorem and advances work by Smiley and Chun for the same problem.
