Краткий обзор статьи: Explicit wave functions for the hierarchy of fractionally quantized Hall states are proposed, and a method for integrating out the quasiparticle coordinates in the spherical geometry is developed. Their energies and overlaps with the exact ground states for small numbers of particles with Coulomb interactions are found to be excellent. We then generalize the adiabatic transport argument of Arovas, Schrieffer, and Wilczek to evaluate quasiparticle charges and statistics, and show that none of the proposed states is the exact ground state of any model Hamiltonian with two-body interactions only.
