Dual interacting cosmologies and late accelerated expansion

TL;DR

This paper demonstrates that a universe with two interacting components can undergo superaccelerated expansion through a dual transformation that preserves Einstein's equations, providing insights into late-time cosmic acceleration.

Contribution

It introduces a dual transformation approach to generate superaccelerated expansion in interacting cosmologies, linking decelerated and accelerated phases.

Findings

Superaccelerated expansion achieved from decelerated universe

Dual transformation preserves Einstein's equations

Potential implications for understanding late-time acceleration

Abstract

In this paper we show that by considering a universe dominated by two interacting components a superaccelerated expansion can be obtained from a decelerated one by applying a dual transformation that leaves the Einstein's field equations invariant.
