Inflation, cosmological perturbations and the recent data


I will present a brief review of cosmic inflation. Then I will discuss the basics of cosmological perturbation theory and explain how it can be used to check inflationary models in observations of the CMB. Finally, I will tell about the recent data and their significance, and especially the discovery of the B-mode polarisation whose origin goes back to primordial gravitational waves.
