A tomographic description for classical and quantum cosmological
  perturbations
  Classical and quantum perturbations can be described in terms of marginal
distribution functions in the framework of tomographic cosmology. In
particular, the so called Radon transformation and the mode-parametric quantum
oscillator description can give rise to links between quantum and classical
regimes. The approach results a natural scheme to discuss the transition from
the quantum to the classical perturbations and then it could be a workable
scheme to connect primordial fluctuations with the today observed large scale
structure.
