论文摘要
我们研究基于比例依赖性重力的宇宙学模型的状态基因参数。有效的爱因斯坦场方程来自平均有效的动作。从动力学系统中,我们得出了改善数值解决方案收敛性的分析表达式。我们确定适度红移的状态基参数,并将其与$λ$ CDM进行比较。
We study the statefinder parameters of a cosmological model based on scale-dependent gravity. The effective Einstein field equations come from an average effective action. From the dynamical system, we derive analytical expressions that improve the convergence of the numerical solutions. We determine the statefinder parameters for moderate redshift and compare them with well-known alternatives to $Λ$CDM.
