Quasi-Rip universe induced by the fluid with inhomogeneous equation of state

TL;DR

This paper explores a dark energy model leading to Quasi-Rip cosmology, where the universe undergoes a transition from phantom to non-phantom phases based on an inhomogeneous equation of state.

Contribution

It introduces a specific fluid model with an inhomogeneous equation of state that induces the Quasi-Rip cosmological scenario.

Findings

Conditions for Quasi-Rip emergence derived

Equation of state parameters analyzed

Transition between phantom and non-phantom phases described

Abstract

We investigate a specific model for dark energy, which lead to the Quasi-Rip cosmology. In the Quasi-Rip model, the equation of the state parameter $w$ is less than -1 in the first stage, but then in the second stage is larger than -1. The conditions for the appearance the Quasi-Rip in the terms of the parameters equation of state are received.
