Fluid inflation with brane correction

TL;DR

This paper explores how inhomogeneous viscous fluids, influenced by brane corrections from string-inspired gravity, can drive early universe inflation and transition to decelerated expansion.

Contribution

It demonstrates viable inflationary solutions incorporating brane corrections and shows the transition back to classical Einstein gravity post-inflation.

Findings

Viable inflationary solutions with brane corrections.

Transition from inflation to decelerated expansion.

Recovery of classical gravity after inflation.

Abstract

In this paper, we have investigated the possibility to have inflation from inhomogeneous viscous fluids by taking into account the brane correction coming from string-inspired five dimensional Einsten's gravity. We have realized several kinds of viable solutions for early-time acceleration. At the end of inflation, the classical Einstein's gravity is recovered and fluids produce decelerated expansion.
