摘要：

The author describes the critical behaviour of wavefunctions at the Anderson metal-insulator transition in terms of fractal measures. At the mobility edge the wavefunctions have structure on all lengths and they scale with a continuous set of non-related exponents Dq. The results are compared with field-theoretic calculations by Wegner (1980) in d=2+ in .
