Hyperbolic Scenario of Accelerating Universe in Modified Gravity

چکیده

Throughout this study, locally rotationally symmetric (LRS) Bianchi type-V space-time is pondered with Tsallis holographic dark energy (THDE) the Granda–Oliveros (GO) cut-off in Sáez–Ballester (SB) theory of gravity. A parameterization deceleration parameter (q) has been suggested: q=α−βH2. The proposed demonstrates Universe’s phase transition from early to current acceleration. Markov chain Monte Carlo (MCMC) was utilized have best-fit value for our model and confirm that satisfies recent observational data. Additional parameters such as q cosmographic jerk, snap, lerk also observed physically graphically. constructed differentiated other models using statefinder pair analysis. Some important features are discussed geometrically.

Accelerating Universe in Modified Theories of Gravity

We study cosmologies in modified theories of gravity considering Lagrangian density f(R) which is a polynomial function of scalar curvature (R) in the Einstein-Hilbert action in vacuum. The field equation obtained from the modified action corresponding to a Robertson-Walker metric is highly non-linear and not simple enough to obtain analytic solution. Consequently we adopt a numerical technique...

Scalar - tensor gravity in an accelerating universe

We consider scalar-tensor theories of gravity in an accelerating universe. The equations for the background evolution and the perturbations are given in full generality for any parametrization of the Lagrangian, and we stress that apparent singularities are sometimes artifacts of a pathological choice of variables. Adopting a phenomenological viewpoint, i.e., from the observations back to the t...

Gauge/gravity correspondence in accelerating universe

We discuss time-dependent backgrounds of type IIB supergravity realizing gravitation duals of gauge theories formulated in de Sitter space-time as a tool of embedding de Sitter in a supergravity. We show that only the gravitational duals to non-conformal gauge theories are sensitive to a specific value of a Hubble parameter. We consider two nontrivial solutions of this type: a gravity dual to s...

Variable Modified Chaplygin Gas and Accelerating Universe

In this letter, I have proposed a model of variable modified Chaplygin gas and shown its role in accelerating phase of the universe. I have shown that the equation of state of this model is valid from the radiation era to quiessence model. The graphical representations of statefinder parameters characterize different phase of evolution of the universe. All results presented in the letter concer...

Accelerating Universe from Modified Kasner Model in Extra Dimensions

We find the power-law solutions in (4+n)-dimensional cosmology with time-varying cosmological constant and study the phase of cosmic evolution. The model corresponds to the modification of the higher dimensional vacuum Kasner model. When a dimensionfull parameter in the model takes special value, it is shown that 4-dimensional universe is accelerated expansion. ∗[email protected]
