An Introduction to Cosmic Inflation Theory

Abstract

This thesis provides a detailed derivation of the Friedmann Equations in the frame work of general relativity and for an FLRW universe. An introduction to the theory of cosmic inflation, the motivations for it, and, the scalar field dynamics associated with inflation presently follows. It further attempts to discuss models of inflation and endeavors to make a classical introduction to cosmological perturbations gen erated in the course of inflation, which are thought to be the originator of structure in the universe. Our metric signature is (+, −, −, −) and we will use the Einstein summation convention.
