Query: A first step towards the inflationary trans-planckian problem treatment
  in Loop Quantum Cosmology   For most initial conditions, cosmologically relevant physical modes were
trans-planckian at the bounce time, often by many magnitude orders. We improve
the usual loop quantum cosmology calculation of the primordial power spectra --
in the inflationary framework -- by accounting for those trans-planckian
effects through modified dispersion relations. This can induce drastic changes
in the spectrum, making it either compatible or incompatible with observational
data, depending on the details of the choices operated.
