Two fluid axially symmetric cosmological models in f(R,T) theory of gravitation

Abstract

In this paper we have investigated two fluid axially symmetric cosmological models in $f(R, T)$ theory of gravitation. To get the deterministic model, we have assumed a supplementary condition $H_3=k H_1$, where $H_1$ and $H_3$ are Hubble parameters and $k$ is constant. Two-fluid model in $f(R, T)$ theory of gravitation, one fluid represents the matter content of the universe and another fluid is chosen to model the cosmic microwave background radiation. Some geometric aspects of the model are also discussed.

Energy Conditions with Interacting Field in f(R) Gravity

“…Another investigation focused on two fluid axially symmetric cosmological models in the f (R, T ) theory of gravitation. By imposing a supplementary constraint H 3 = kH 1 , the authors [31] obtained a deterministic model that exhibited an expanding and shearing Universe. Some authors [32] presented a FRW cosmological model which satisfied the principle and considering the most recent research that suggested dark energy is responsible for the Universe's acceleration.…”
