Abstract

In this paper we present the study of the scalar cosmological perturbations of a single field inflationary model up to first order in deviation. The Christoffel symbols and the tensorial quantities are calculated explicitly in function of the cosmic time t. The Einstein equations are solved up-to first order in deviation and the scalar perturbations equation is derived.
