Stability of Kaluza–Klein holographic dark energy cosmological models in f(R) theory of gravitation

Autor: R. J. Baxi, S. D. Katore

Publikováno v: Indian Journal of Physics. 93:1501-1514

We study Kaluza–Klein space–time in the context of f(R) theory of gravitation in the presence of minimally interacting holographic dark energy. Exact solutions of field equations are obtained for volumetric exponential expansion, power law expans

Hypersurface Homogeneous Cosmological Model in Modified Theory of Gravitation

Autor: R. J. Baxi, Shivdas D. Katore, S. P. Hatkar

Publikováno v: Astrophysics. 59:525-539

We study a hypersurface homogeneous space-time in the framework of the f (R, T) theory of gravitation in the presence of a perfect fluid. Exact solutions of field equations are obtained for exponential and power law volumetric expansions. We also sol

Domain wall cosmological models with deceleration parameter in modified theory of gravitation

Autor: S. P. Hatkar, Shivdas D. Katore, R. J. Baxi

Publikováno v: Chinese Journal of Physics. 54:563-573

In this study, we intend to explore the Friedmann–Robertson–Walker (FRW) metric and an axially symmetric space-time in the presence of a thick domain walls in the framework of f ( R, T ) theory of gravitation, where R is the Ricci scalar and T is

Unified Description of Bianchi Type-I Universe in $$f\,(R)$$ f ( R ) Gravity

Autor: R. J. Baxi, Shivdas D. Katore, S. P. Hatkar

Publikováno v: Foundations of Physics. 46:409-427

The present study explores the Bianchi type I universe in the frame work of f(R) theory of gravity by considering strange quark matter attached to string cloud and domain walls in the presence and absence of magnetism. Field equations are solved by c
