Abstract
The nature of the transition from the non-metallic spin glass to the s uperconducting regime in high-T(c) superconductors is discussed. It is concluded that bosons exist already in the former, and that the trans ition is of Anderson type. States in a two-dimensional lattice appear to show a mobility edge, probably separating exponential and power-law states, thus contradicting some results of scaling theory.
