The role of Lorentz invariance and pomeron loops in the evolution, the relation between high-energy QCD and statistical physics and results for the saturation momentum and the scattering amplitude are discussed.4 pages, Talk given at 15th International Workshop on Deep Inelastic Scattering (DIS07), Munich, Germany, April 16-20, 2007High Energy Physics - Phenomenologytext
