LRS Bianchi I model with perfect fluid equation-of-state

Abstract: The general solution of the field equations in LRS Bianchi-I space-time with perfect fluid equation-of-state (EoS) is presented. The models filled with dust, vacuum energy, Zel'dovich matter and disordered radiation are studied in detail. A unified and systematic treatment of the solutions is presented, and some new solutions are found. The dust, stiff matter and disordered radiation models describe only a decelerated universe, whereas the vacuum energy model exhibits a transition from a decelerated to an acce… Show more

“…In other words, the energy density of matter must be positive. This procedure has been followed in many earlier works [67,68,69,70,71,72,73,74,75] (see also our recent work [66] and references therein).…”

“…In particular, the Locally-Rotationally-Symmetric (LRS) B-I spacetime is one of the simplified versions of the B-I model. In light of its importance, many researchers have studied the LRS B-I models in various contexts (see [8][9][10][11][12] and references therein).…”
