Query: A Holographic Fractional Topological Insulator   We give a holographic realization of the recently proposed low energy
effective action describing a fractional topological insulator. In particular
we verify that the surface of this hypothetical material supports a fractional
quantum Hall current corresponding to half that of a Laughlin state.
