Abstract

One of the major objectives of this dissertation has been the seek for inflationary models, coming from supersymmetric theories, which are compatible with recent cosmological data and, more specifically, with measurements of the spectral index from the WMAP3 data. A particular particle physics model, the extended SUSY Pati-Salam model with Yukawa quasi-unification, was examined thoroughly with respect to its cosmology and it was found that it incorporates a number of inflationary scenarios which can become compatible with recent data. The study of these scenarios brought out variations of cosmological models which might be important in cosmological research.
