Effects of Hard Influence of Dark SectorFields on Cosmological Perturbations

Abstract

We consider Dark Sector fields evolution on the basis of dynamical equations on the background
of inflationary stage of Universe. We consider energy characteristics of Dark Sector
fields to be of the same order as perturbations of gravitation field and inflaton. Effects of
influence of Dark Sector fields on large-scale structure formation within the example of exponential
inflation are researched.
