Query: A central limit theorem for random closed geodesics: proof of the
  Chas-Li-Maskit conjecture   We prove a central limit theorem for the length of closed geodesics in any
compact orientable hyperbolic surface. In the special case of a hyperbolic pair
of pants, this settles a conjecture of Chas-Li-Maskit.
