Query: Carleman estimate and unique continuation for a structured population
  model   We consider a time-dependent structured population model equation and
establish a Carleman estimate. We apply the Carleman estimate to prove the
unique continuation which means that Cauchy data on any lateral boundary
determine the solution uniquely.
