Abstract: Fractional Quantum Hall Effect (FQHE) describes electronic gas in quantizing magnetic field. In realistic setting electrons are confined in a plane. However, many subtle properties of this phenomena are revealed and better understood would electronic liquid be placed on a Riemann surface instead. Then a response of electronic liquid to a change of the geometry (metric) generates sensible physical information. In return FQHE on Riemann surfaces fosters sensible geometric objects and structures yet to be understood.
