Query: A note on Fisher Information hypocoercive decay for the linear Boltzmann
  equation   This note deals with the linear Boltzmann equation in the non-compact setting
with a confining potential which is close to quadratic. We prove that in this
case, starting from a smooth initial datum, the Fisher Information (hence, the
relative entropy) with respect to the stationary state converges exponentially
fast to zero.
