Bianchi type-I cosmological models with time dependent q and Λ-term in general relativity

Autor: Rekha Jaiswal, Anirudh Pradhan, Rajeev Kumar Khare

Publikováno v: Astrophysics and Space Science. 343:489-497

On getting motivation from increasing evidence for the need of a geometry that resembles Bianchi morphology to explain the observed anisotropy in the WMAP data, Einstein’s field equations with variable cosmological “constant” are considered in

Publikováno v: Astrophysics and Space Science. 337:401-413

We present two dark energy (DE) models with an anisotropic fluid in Bianchi type-VI 0 space-time by considering time dependent deceleration parameter (DP). The equation of state (EoS) for dark energy ω is found to be time dependent and its existing
