Abstract
We study the field theory approach to Anderson localization paying special attention to the way in which localized states avoid Goldstone's theorem. We provide a formal derivation of Wegner's non-linear σ model for the localization transition and discuss those properties which are unusual, but necessary, if it is to give a correct description of physics near the mobility edge. © 1981.
