LRS Bianchi Type I Models with Anisotropic Dark Energy and Constant Deceleration Parameter

Understand

Locally rotationally symmetric (LRS) Bianchi Type I cosmological models are examined in the presence of dynamically anisotropic dark energy and perfect fluid.

• We assume that the dark energy (DE) is minimally interacting, has dynamical energy density, anisotropic equation of state parameter (EoS).
• The conservation of the energy-momentum tensor of the DE is assumed to consist of two separately additive conserved parts.
• A special law is assumed for the deviation from isotropic EoS, which is consistent with the assumption on the conservation of the energy-momentum tensor of the DE.
