Singular inflation from Born-Infeld-f(R) gravity

TL;DR

This paper explores a simplified Born-Infeld-$f(R)$ gravity model that unifies early inflation and late-time acceleration, aligning with Planck data, without involving matter fields.

Contribution

It introduces a novel singular inflation model within Born-Infeld-$f(R)$ gravity that unifies cosmic acceleration phases in a matter-free, conformal framework.

Findings

Model achieves unification of inflation and late-time acceleration.

Results are consistent with latest Planck data.

Simplified conformal approach without matter fields.

Abstract

Accelerating dynamics from Born-Infeld-$f(R)$ gravity are studied in a simplified conformal approach without matter. Explicit unification of inflation with late-time acceleration is realized within this singular inflation approach, which is similar to Odintsov-Oikonomou singular $f(R)$ inflation. Our model turns out to be consistent with the latest release of Planck data.
