Variable Modified Chaplygin Gas and Accelerating Universe

TL;DR

This paper proposes a variable modified Chaplygin gas model that explains the universe's acceleration, valid from radiation to dark energy eras, with statefinder parameters illustrating different evolutionary phases.

Contribution

It introduces a novel variable modified Chaplygin gas model and analyzes its role in cosmic acceleration across different universe phases.

Findings

Model explains universe acceleration from radiation to dark energy eras

Statefinder parameters characterize different evolutionary phases

Results focus on flat universe case (k=0)

Abstract

In this letter, I have proposed a model of variable modified Chaplygin gas and shown its role in accelerating phase of the universe. I have shown that the equation of state of this model is valid from the radiation era to quiessence model. The graphical representations of statefinder parameters characterize different phase of evolution of the universe. All results presented in the letter concerns the case $k=0$.
