“…Its present value is sufficiently small (−0.02 approximately), indicating a small anisotropy in the present universe, which becomes smaller with time. This behaviour is consistent with the observation of a recent study on anisotropic dark energy model in the Kaluza-Klein framework [28].…”

“…The barotropic equation of state (EoS) parameter for the normal dimensions is 𝜔𝜔𝜔𝜔 = 𝑝𝑝𝑝𝑝/𝜌𝜌𝜌𝜌. Based on some studies on anisotropy, in the framework of Kaluza-Klein theory, we have used the equation, 𝑝𝑝𝑝𝑝 𝜓𝜓𝜓𝜓 = (𝛿𝛿𝛿𝛿 + 𝜔𝜔𝜔𝜔)𝜌𝜌𝜌𝜌, as the directional equation of state for the fifth dimension, where 𝛿𝛿𝛿𝛿 is the skewness parameter which represents the deviation from the normal equation-of-state parameter 𝜔𝜔𝜔𝜔 [28,[36][37][38][39][40][41]. The parameter 𝛿𝛿𝛿𝛿 serves as measure of deviation from isotropy.…”

“…This has prompted many cosmologists to explore the study of models with dark energy fluid. Cheng et al [7], and Jain [8] have studied dark energy-dark matter interactive models with varied perspectives. These interactive DE-DM models are studied extensively nowadays.…”
