String Cosmology in LRS Bianchi Type-II Dusty Universe with Time Decaying Vacuum Energy Density

Hassan Amirhashchi

A model of a cloud formed by massive strings is used as a source of LRS Bianchi type II with time decaying vacuum energy density . To construct string cosmological models we hav…

L.R.S. Bianchi type II Stiff Fluid cosmological model with Decaying Vacuum Energy Density in general relativity

Hassan Amirhashchi

Locally rotationally symmetric (L.R.S.) Bianchi type II stiff fluid cosmological model is investigated. To get the deterministic model of the universe, we have assumed a condition…

An Interacting Two-Fluid Scenario for Dark Energy in FRW Universe

Hassan Amirhashchi, Anirudh Pradhan, Bijan Saha

We study the evolution of the dark energy parameter within the scope of a spatially flat and isotropic Friedmann-Robertson-Walker (FRW) model filled with barotropic fluid and dark…

Dark Energy Model in Anisotropic Bianchi Type-III Space-Time with Variable EoS Parameter

Anirudh Pradhan, Hassan Amirhashchi

A new dark energy model in anisotropic Bianchi type-III space-time with variable equation of state (EoS) parameter has been investigated in the present paper. To get the determinis…

Bianchi Type-I Anisotropic Dark Energy Models with Constant Deceleration Parameter

Anirudh Pradhan, H. Amirhashchi, Bijan Saha

New dark energy models in anisotropic Bianchi type-I (B-I) space-time with variable EoS parameter and constant deceleration parameter have been investigated in the present paper. T…
