Cosmological models with a Hybrid Scale Factor

TL;DR

This paper reviews cosmological models using a Hybrid Scale Factor within general relativity, highlighting their ability to replicate early deceleration and late-time acceleration of the universe.

Contribution

It introduces and discusses the dynamical behavior of cosmological models with HSF under various matter fields, emphasizing their relevance to current universe observations.

Findings

HSF models exhibit early deceleration and late acceleration.

Models can mimic the present universe dynamics.

Dynamical aspects depend on matter fields.

Abstract

In this brief review, we present some cosmological models with a Hybrid Scale Factor (HSF) in the framework of general relativity (GR). The hybrid scale factor fosters an early deceleration as well as a late time acceleration and mimics the present Universe. The dynamical aspects of different cosmological models with HSF in the presence of different matter fields have been discussed.
