Query: Return time statistics for invariant measures for interval maps with
  positive Lyapunov exponent   We prove that multimodal maps with an absolutely continuous invariant measure
have exponential return time statistics around a.e. point. We also show a
`polynomial Gibbs property' for these systems, and that the convergence to the
entropy in the Ornstein-Weiss formula has normal fluctuations. These results
are also proved for equilibrium states of some Hoelder potentials.
