Energy conditions constraints on a class of f(R)-gravity
摘要：
在度量变分方法的框架下，给出并讨论了一般f（R）泛函形式的能量条件的界。作为能量条件在局部齐性和各向同性f（R）宇宙学中的具体应用，本文利用最近的减速度和加加速度参数的估计值，考察了f（R）= \sqrt{R^2 - R_0^2}引力理论族自由参数在弱能量条件下的界.
英文摘要：
We present and discuss the bounds from the energy conditions on a general f(R) functional form in the framework of metric variational approach. As a concrete application of the energy conditions to locally homogeneous and isotropic f(R)-cosmology, the recent estimated values of the deceleration and jerk parameters are used to examine the bounds from the weak energy condition on the free parameter of the family of f(R)=\sqrt{R^2 - R_0^2} gravity theory.
