Query: Remark on the Kato smoothing effect for Schr\"odinger equation with
  superquadratic potentials   The aim of this note is to extend recent results of Yajima-Zhang \cite{Y-Z1,
Y-Z2} on the 1/2- smoothing effect for Schr\"odinger equation with potential
growing at infinity faster than quadratically.
