Perturbations in loop quantum cosmology
  The era of precision cosmology has allowed us to accurately determine many
important cosmological parameters, in particular via the CMB. Confronting Loop
Quantum Cosmology with these observations provides us with a powerful test of
the theory. For this to be possible we need a detailed understanding of the
generation and evolution of inhomogeneous perturbations during the early,
Quantum Gravity, phase of the universe. Here we describe how Loop Quantum
Cosmology provides a completion of the inflationary paradigm, that is
consistent with the observed power spectra of the CMB.
