Query: Local well-posedness for third order Benjamin-Ono type equations on the
  torus   We consider the Cauchy problem of third order Benjamin-Ono type equations on
the torus. Nonlinear terms may yield derivative losses, which prevents us from
using the classical energy method. In order to overcome that difficulty, we add
a correction term into the energy. We also use the Bona-Smith type argument to
show the continuous dependence.
