Query: Time-reversal symmetric hierarchy of fractional incompressible liquids   We provide an effective description of fractional topological insulators that
include the fractional quantum spin Hall effect by considering the
time-reversal symmetric pendant to the topological quantum field theories that
encode the Abelian fractional quantum Hall liquids. We explain the hierarchical
construction of such a theory and establish for it a bulk-edge correspondence
by deriving the equivalent edge theory for chiral bosonic fields. Further, we
compute the Fermi-Bose correlation functions of the edge theory and provide
representative ground state wave functions for systems described by the bulk
theory.
