Five Dimensional Little Rip Cosmological Models In General Relativity

In this paper, we have investigated flat Friedmann-Robertson-Walker type Kaluza-Klein model in the presence of ideal fluid with quadratic equation of state(EoS) with time dependent parameters ω(t) and (Λt). We have investigated the properties of ω(t) and found that for Little Rip model ω(t) = −1 and...

Zusammenfassung:In this paper, we have investigated flat Friedmann-Robertson-Walker type Kaluza-Klein model in the presence of ideal fluid with quadratic equation of state(EoS) with time dependent parameters ω(t) and (Λt). We have investigated the properties of ω(t) and found that for Little Rip model ω(t) = −1 and for Pseudo Rip model ω(t) < −1. Also, we have studied behaviour of Little Rip(LR) and Pseudo Rip(PR) for dark energy. For obtained LR and PR models we have estimated the disintegration time.
