Towards the unification of late-time acceleration and inflation by k-essence model

TL;DR

This paper constructs a cosmological model using k-essence to unify early universe inflation and late-time acceleration, based on a recent reconstruction formulation.

Contribution

It explicitly develops a unified cosmological model combining inflation and late-time acceleration using the k-essence framework.

Findings

Successful unification of inflation and late-time acceleration

Application of reconstruction method to k-essence

New insights into cosmological evolution

Abstract

Based on the formulation of the reconstruction for the k-essence model, which was recently proposed in arXiv:1001.0220 [hep-th], we explicitly construct cosmological model to unifying the late-time acceleration and the inflation in the early universe.
