论文摘要
在许多扩展的重力理论中，$ f（r，t）$重力在近期获得了合理的兴趣，因为它在宇宙学方面提供了有趣的结果。经过广泛研究了重力理论中的对数校正。在这项工作中，我们考虑了对痕迹t的对数校正，并将功能形式作为$ f（r，t）= r +16πgα\ ln t $，其中$α$是一个免费参数。使用深色能量密度参数$ω_λ$和哈勃参数$ H_0 $来限制自由参数。发现下限为$α\ ge -9.85 \ times 10^{ - 29} $。还研究了宇宙学的含义。
Of many extended theories of gravity, $f(R,T)$ gravity has gained reasonable interest in recent times as it provides interesting results in cosmology. Logarithmic corrections in modified theories of gravity has been studied extensively. In this work, we considered logarithmic correction to the trace term T and take the functional form as $f(R,T)=R + 16 πG α\ln T$ where $α$ is a free parameter. The free parameter is constrained using dark energy density parameter $Ω_Λ$ and Hubble parameter $H_0$. The lower bound is found to be $α\ge - 9.85 \times 10^{-29}$. The cosmological implications are also studied.
