Abstract
This is a pedagogical introduction to early cosmology and the host of fundamental physics involved in it (particle physics, grand unification and general relativity). Inflation and the inflaton field are the central theme of this review. The quantum field treatment of the inflaton is presented including its out of equilibrium evolution and the use of nonperturbative methods. The observational predictions for the CMB anisotropies are briefly discussed. Finally, open problems and future perspectives in connection with dark energy and string theory are overviewed.
