Bouncing Behavior of Kaluza-Klein Cosmological Model in General Relativity

H. R. Ghate, Atish S. Sontakke & Yogendra D. Patil · Physical Science International Journal · 2016

Kaluza-Klein cosmological model has been obtained in the general theory of relativity. The source for energy-momentum tensor is assumed a perfect fluid. The field equations have been solved by using a special form of the average scale factor  proposed by Cai et al. [10]. The phys...

Bianchi Type-IX Cosmological Model with a Perfect Fluid in f(R) Theory of Gravity

H. R. Ghate & Atish S. Sontakke · Physical Science International Journal · 2015

Bianchi type-IX space-time is considered in the framework of the ƒ(R) theory of gravity when the source of the energy momentum tensor is a perfect fluid. The cosmological model is obtained by using the condition that the expansion scalar (θ) is proportional to the shear scalar (σ...
