چکیده
In this paper, we consider the correspondence between tachyon dark energy model and Tsallis holographic scenario in an FRW universe.We demonstrate description of universe reconstruct potential basic results dynamics scalar field which describe cosmology. a flat universe, energy, independent existence interaction matter or not, \dot{T}^2 must always be zero. Therefore, equation state {\omega}_D is -1 such universe. For non-flat cannot zero so that {\omega}_D=-1 used to explain origin cosmological constant. monotonically decreases with increase \cos(R_h/a) \cosh(R_h/a) for different {\delta}'s. particular, open larger than zero, while closed smaller zerowhich physically invalid. addition, conclude \cosh(R_h/a), irrespective value b^2.

Generalized Holographic Dark Energy Model
In this paper, the model of the holographic Chaplygin gas has been extended to two general cases: first the case of a modified variable Chaplygin gas and second the case of the viscous generalized Chaplygin gas. The dynamics of the model is expressed by the use of scalar fields and scalar potentials.
متن کاملStatefinder Parameters for Tachyon Dark Energy Model
In this paper we study the statefinder parameters for the tachyon dark energy model. There are two kinds of stable attractor solutions in this model. The statefinder diagrams characterize the properties of the tachyon dark energy model. Our results show that the evolving trajectories of the attractor solutions lie in the total region and pass through the LCDM fixed point, which is different fro...
متن کاملA Model of Holographic Dark Energy
A model for holographic dark energy is proposed, following the idea that the short distance cut-off is related to the infrared cut-off. We assume that the infrared cut-off relevant to the dark energy is the size of the event horizon. With the input ΩΛ = 0.73, we predict the equation of state of the dark energy at the present time be characterized by w = −0.90. The cosmic coincidence problem can...
متن کاملGeneralized Interacting Holographic Dark Energy Model
In this manuscript, we present a generalization of the interacting holographic dark energy model using two equations of states for the dark energy: the modified variable Chaplygin gas and the viscous generalized Chaplygin gas. The dynamics of the model are expressed by the use of scalar fields and the scalar potentials. PACS numbers: 98.80.Cq, 98.80.-k, 98.80.Jk ∗[email protected]
متن کاملStatefinder diagnostic for holographic dark energy model
In this paper we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with c = 1 in the statefinder parameter-planes. The statefinder diagrams characterize the properties of the holographic dark energy and show the discrimination between this scenario and other dark energy models. We also perform a statefinder ...
