Inflationary Universe with a Viscous Fluid Avoiding Self-Reproduction

TL;DR

This paper proposes a cosmological model with a viscous fluid that achieves inflation without self-reproduction, aligning well with recent PLANCK data.

Contribution

It introduces a viscous fluid model that sustains inflation while avoiding self-reproduction, a novel approach in cosmological inflation theories.

Findings

Model aligns with PLANCK data

Inflation occurs without self-reproduction

Conditions for inflation with viscous fluid derived

Abstract

We consider a universe with a bulk viscous cosmic fluid, in a flat Friedmann-Lemaitre-Robertson-Walker geometry. We derive the conditions for the existence of inflation, and those which at the same time prevent the occurrence of self-reproduction. Our theoretical model gives results which are in perfect agreement with the most recent data from the PLANCK surveyor.
