An accelerated universe with negative equation of state parameter in Inhomogeneous Cosmology with -essence scalar field

Somnath Mukherjee, Debashis Gangopadhyay

We obtain a scaling relation for spherically symmetric k-essence scalar fields for an inhomogeneous cosmology with the Lemaitre-Tolman- Bondi (LTB) metric. We show that th…

k-essence classical Hamiltonian approach for an accelerated expansion of the Universe with

Somnath Mukherjee

We obtain lagrangian for -essence scalar field with scalar curvature of Friedmann-Lemaitre-Robertson-Walker (FLRW) metric . Obtained lagrangian has two generalised…

On A Cosmological Invariant as an Observational Probe in the Early Universe

Debashis Gangopadhyay, Somnath Mukherjee

k-essence scalar field models are usually taken to have lagrangians of the form with some general function of . Under certain con…
