Abstract
It is shown that the behavior of Anderson localization near the mobility edge is described by a noncompact nonlinear model in dimensions. The explicit calculation in perturbation gives one-to-one correspondence with the effective Hamiltonian of the nonlinear model. The renormalization-group function and the anisotropic effect are discussed.
