Some studies on k essence Lagrangian

TL;DR

This paper investigates the k-essence Lagrangian during the early universe, showing it can lead to accelerated expansion driven by dark energy's negative pressure.

Contribution

It provides new insights into the behavior of k-essence models in the early universe and their role in cosmic acceleration.

Findings

K-essence Lagrangian causes accelerated expansion in early universe

Dark energy's negative pressure drives early universe acceleration

Equation of state parameter indicates dark energy dominance

Abstract

K-essence Lagrangian is studied in the context of an early universe epoch when time is very small. Equation of state parameter as well as deceleration parameter , indicates an accelerated expansion of the universe at an early epoch of time driven by negative pressure generated by dark energy.
