Abstract: Anderson localization is influenced by interaction effects in various ways. First, interaction processes destroy the phase coherence and limit localization at finite temperature in all dimensions. Secondly, interaction gives rise to a new type of quantum correction to the conductivity. Thirdly, the metal-insulator transition is modified by interaction effects in ways not completely understood yet. I review the renormalization group theory of disordered interacting electron systems. Finally, a comparison with experimental data on selected systems is presented.
