Different aspects of the localization of waves by  disorder, nonlinearity and else... a short review

We review some aspects of the localization of waves in discrete lattices. We  first recall what is Anderson localization. An example of Anderson localization in nonrandom lattices which are quasiperiodic will be described in details. We shall also discuss its differences with Anderson localization in random systems. Localization by nonlinearity and the theory of discrete breathers will be next shortly reviewed. We shall finish by discussing open problems about localization of waves in nonlinear random systems with linear Anderson localization.
