Metallic conduction, apparent metal-insulator transition and related   phenomena in two-dimensional electron liquid
  The lecture introduces a reader to the relatively young field of physics of strongly interacting and disordered 2D electron system, in particular, to the phenomena of the metallic conduction and the apparent metal-insulator transition in 2D. The paper briefly overviews the experimental data on the electron transport, magnetotransport, spin-magnetization in 2D, and on the electron-electron interaction effects.
