We dedicate this chapter to inflation, a model of the primordial universe in which an almost constant H provides a scale factor a growing exponentially with the cosmic time. Inflation is able to solve some puzzles related to background cosmology and also to provide a testable prediction of the power spectrum of primordial fluctuations. Among the first pioneering works on inflation there are Starobinsky (JETP Lett 30:682–685, 1979), Guth (Phys Rev D 23:347–356, 1981), Linde (Phys Lett 108B:389–393, 1982) and Albrecht and Steinhardt (Phys Rev Lett 48:1220–1223, 1982).
