Bouncing Cosmological Models in a Functional form of \(\boldsymbol{F(R)}\) Gravity
We investigate some bouncing cosmological models in an isotropic and homogeneous space-time with in \(F(R)\) theory of gravity. Two functional forms of \(F(R)\) have are studied with a bouncing scale factor. The dynamical parameters are derived and analyzed along with cosmographic parameters. A violation of sthe trong energy conditions in both bouncing models is also shown. We show that both models exhibit stable behavior with respect to cosmic time.
期刊介绍：
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
