Abstract:I will present analitical theory of superconductivity of weakly localized electrons ( near Anderson mobility edge) and of the quantum phase transition from this unusual superconductive state to the hard-gap insulator.  An issue of many-body localization and energy transport in strongly interacting system will be discussed as well.  This talk will based on the results presented in the papers:
