These equations lead to corresponding unitarization schemes in the impact parameter representation of the hadron scattering amplitude. It is shown how specific properties of the non-linear equations reflect different features of the diffraction processes.7 pages, 5 figures, needs PoS.cls and PoSlogo, contribution to the proceedings of the International Workshop on Diffraction in High-Energy Physics "DIFFRACTION 2006", Adamantas, Milos island, Greece, September 5 - 10, 2006High Energy Physics - Phenomenologytext
