چکیده

In this paper, we considered the study of Friedmann-Robertson-Walker (FRW) model in framework $f(Q,T)$ gravity, an extension symmetric teleparallel recently defined by Y. Xu et al. \cite{Xu}. The non-linear $f(Q,T)=-\alpha Q-\beta T^2$, where $\alpha>0$ and $\beta>0$ are constants, is taken into account. equation state perfect fluid assumed 31 points Hubble data used to constrain value parameter. To explore evolution universe, numerical solutions cosmological implications such as parameter, deceleration apparent magnitude luminosity distance determined energy conditions examined. theoretical results parameter compared with $\Lambda$CDM model. Further, 57 Supernova (42 from cosmology project 15 Cal\'{a}n/ Tolono supernova survey) also have consistent distance.

Viscous Frw Cosmology in Modified Gravity

We discuss a modified form of gravity implying that the action contains a power α of the scalar curvature. Coupling with the cosmic fluid is assumed. As equation of state for the fluid, we take the simplest version where the pressure is proportional to the density. Based upon a natural ansatz for the time variation of the scale factor, we show that the equations of motion are satisfied for gene...

Quasilocal Energy in FRW Cosmology

This paper presents a calculation of the quasilocal energy of a generic FRW model of the universe. The results have the correct behavior in the small-sphere limit and vanish for the empty Milne universe. Higher order corrections are found when comparing these results to classical calculations of cosmological energy. This case is different from others in the literature chiefly in that it involve...

Closed FRW model in Loop Quantum Cosmology

The basic idea of the LQC applies to every spatially homogeneous cosmological model, however only the spatially flat (so called k = 0) case has been understood in detail in the literature thus far. In the closed (so called: k=1) case certain technical difficulties have been the obstacle that stopped the development. In this work the difficulties are overcome, and a new LQC model of the spatiall...

Open FRW model in Loop Quantum Cosmology

Open FRW model in Loop Quantum Cosmology is under consideration. The left and right invariant vector fields and holonomies along them are studied. It is shown that in the hyperbolic geometry of k = −1 it is possible to construct a suitable loop which provides us with quantum scalar constraint originally introduced by Vandersloot [19]. Such an operator has correct geometrical interpretation. The...

Modified Averaging Processes in Cosmology and the Structured FRW model

We study the volume averaging of inhomogeneous metrics within GR and discuss its shortcomings such as gauge dependence, singular behavior as a result of caustics, and causality violations. To remedy these shortcomings, we suggest some modifications to this method. As a case study we focus on the inhomogeneous structured FRW model based on a flat LTB metric. The effect of averaging is then studi...
