论文摘要

该论文涉及修改的F(t)重力理论中的宇宙学。通过对功能F(t)功能的某些现象学选择,可以使宇宙学解决方案描述统一和各向同性FLRW模型的宇宙进化的不同阶段。通过正确选择函数$ f(t)$的参数以及宇宙学解决方案中的参数,也表明,从紧急情况开始到当前迟到时间的加速是可以进行连续的宇宙演化。最后,提出了F(t)重力的热力学分析。

The paper deals with cosmology in modified f(T) gravity theory. With some phenomenological choices for the function f(T) it is possible to have cosmological solutions describing different phases of the evolution of the Universe for the homogeneous and isotropic FLRW model. By proper choice of the parameters involved in the function $f(T)$ and also in the cosmological solutions it is shown that a continuous cosmic evolution starting from the emergent scenario to the present late time acceleration is possible. Finally thermodynamical analysis of f(T) gravity is presented.
