Kantowski-Sachs Cosmological model with quark and strange quark matter in f(R) theory of gravity

Abstract

Abstract:In this paper we have studied the KantowskiSachs cosmological model with the quark and strange quark matter in the f (R) theory of gravity. The general solutions of the eld equations are obtained by assuming the physical condition shear scalar σ is proportional to scalar expansion θ, which leads to the relation B = A n between metric coe cients B and A. The physical and geometrical aspects of the model are also discussed.

Magnetized strange quark model with Big Rip singularity in f(R, T) gravity

“…In general theory of relativity, the strange quark matter has been studied along with cosmic string cloud for axially symmetric space-time by Katore 50 and again attached to both string cloud and domain wall for spherically symmetric Kink space-time by Sahoo and Mishra. 51,52 In f (R) theory of gravity, the behaviour of quark and strange quark matter has been studied for Bianchi type-I and V space time by Yilmaz et al 47 and for Kantowski-Sachs metric by Adhav et al 48 In particular, Agrawal and Pawar 49 have studied the quark and strange quark matter for a LRS Bianchi I metric in f (R, T ) gravity. They have solved the field equations using constant deceleration parameter.…”

Plane Symmetric Cosmological Model with Quark and Strange Quark Matter in f (R, T) Theory of Gravity

“…Khadekar & Shelote (2012) have obtained higher dimensional cosmological model in the presence of quark and strange quark matter. Adhav et al (2015) have discussed the Kantowski-Sachs Cosmological model with quark and strange quark matter in f(R) gravity. Rao & Neelima (2014) have studied Bianchi type-VI 0 space-time with strange quark matter attached to string cloud.…”

Anisotropic Cosmological Model with Quark and Strange Quark Matter in f(R, T ) Gravity Theory

“…which despite being quite simple, describes both decelerating and accelerating phases of the universe where α(> 0) and n(> 1) are constants. Solving Equation (19), one can obtain the average scale factor as a = e αnt − 1 α/n .…”

“…Sahoo and Mishra [18] have studied axially symmetric cosmological model with string cloud universe containg strange quark matter. Further Adhav et al [19] have discussed Kantowski-Sachs cosmological model with quark and strange quark matter in f (R) gravity theory. Recently, Agrawal and Pawar [20] have studied plane symmetric cosmological model with quark and strange quark matter in f (R, T ) gravity theory by applying a special law of variation of Hubble parameter that yields a constant value of deceleration parameter.…”
