Early universe inflation and PLANCK/BICEP2 data

The early universe cosmology can be successfully described in the theoretical framework of modified gravity and quintessence. I introduce the Starobinsky and Linde inflationary models in light of the recent CMB observations by the PLANCK satellite mission and the BICEP2 telescope. Preheating and reheating after inflation are briefly reviewed. Some very recent theoretical results about inflation, leptogenesis, dark matter and dark energy in the context of N=1 supergravity are outlined.
