Topics in inflationary cosmologies
The first chapter is an introduction to the standard hot big bang cosmological model. The model and some of the problems associated with it are reviewed. In the second chapter, a short review of the proposals for solving the cosmological conundrums of the big-bang model is presented. The old and the new inflationary scenarios are studied, and some alternative scenarios, especially those using supersymmetry, are reviewed briefly. The third chapter is a study of inflationary models where the same set of fields that breaks supersymmetry is also responsible for inflation. In these models, the scale of supersymmetry breaking is related to the slope of the potential near the origin and can thus be kept low. It was found that a supersymmetry breaking scale of the order of the weak breaking scale, can be obtained. In the fourth chapter, an alternative mechanism for the generation of baryon number within the framework of supergravity inflationary models is studied. The gravitational couplings of the heavy fields with the hidden sector (the sector which breaks supersymmetry are used.
