Abstract: Early universe cosmology can be described in the theoretical framework of modified gravity and quintessence. Our recent results devoted to inflation, pre-heating and re-heating, and their relation to the observational cosmology, are reviewed in the context of f(R) gravity and F(R) supergravity theories. They represent a remarkable mix of experimental observations, computer simulation and numerical calculations, supersymmetry and supergravity, high-energy particle physics, string theory, and mathematical physics.
