The Statefinder hierarchy: An extended null diagnostic for concordance cosmology
expansion factor written in dimensionless form, a/aH, equals unity for ΛCDM. We generalize this result and demonstrate that the hierarchy, a/aH, can be converted to a form that stays pegged at unity in concordance cosmology. This remarkable property of the Statefinder hierarchy enables it to be used as an extended null diagnostic for the cosmological constant. The Statefinder hierarchy, combine...
متن کاملFractional systems and fractional Bogoliubov hierarchy equations.
We consider the fractional generalizations of the phase volume, volume element, and Poisson brackets. These generalizations lead us to the fractional analog of the phase space. We consider systems on this fractional phase space and fractional analogs of the Hamilton equations. The fractional generalization of the average value is suggested. The fractional analogs of the Bogoliubov hierarchy equ...
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 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 ...
متن کاملThe Graph Parameter Hierarchy
The purpose of this document is to gather graph parameters (also called graph invariants) and their relationships in a central place. It was edited by Manuel Sorge and Mathias Weller with contributions by Ondřej Suchý, and Gerhard J. Woeginger. This project and the diagram shown in Figure 1 is inspired by the work of Bart M. P. Jansen [13]. Some further related work (in no particular order) is ...
