Abstract:
The Cosmic Microwave Background (CMB) anisotropies measurements can
provide many clues about the Universe. Although the common belief is
that they will allow a very precise measurement of the cosmological
parameters (that is, the current state of the Universe), they will
alternatively give interesting informations about the state of the
initial perturbations (that is, the state of the Universe at the end
of inflation). In this paper, we study the observational
consequences on the CMB anisotropies of some wide set of inital
conditions, with a correlated mixture of adiabatic and isocurvature
perturbations.
