Abstract The Friedmann Robertson Walker FRW metric is given using the homogeneity and isotropy principles For this metric and for a perfect fluid the Einstein equations are solved and result in the Friedmann equations The standard model of cosmology encounters with horizon and flatness The inflation model is a solution for such problems During inflation Hubble radius is reduced and this make to justify the problems of standard cosmology In inflationary models the slow roll condition is necessary for inflating the space time This condition is given by a flat potential Moreover the quantum fluctuations of inflaton field can explain the large scale structures The basic parameter in large scale study is the curvature perturbation It has been formulated a large class of models for inflation which gives a scale invariant curvature perturbation on large scales In study of inflation period as far as we represent various types of inflation models that now we check some general samples and we research by means of using diagram correlative condition for inflation period and end of it In this thesis we study the power low model for inflation The main problem of power law inflation is that there is no graceful exist i e inflation does not finished Here we consider a potential giving rise to power law inflation with waterfall like potential The waterfall field is on its vacuum until the end of inflation Then the waterfall field roles down and inflation is over We investigate this paradigm numerically and the results show a successful graceful exists for power law inflation Keywords Standard cosmological model Inflation model Power spectrum Spectral index Commoving curvature perturbation Power law inflation model Graceful exit PDF created with pdfFactory trial version www pdffactory com
