论文摘要
在本文中，我们探索了$ f（t，b）$ gravity的字段方程，并用哈勃参数的双曲线函数确定了动力学参数。已经观察到加速行为，状态参数方程的行为表明$λCDM$模型在很晚。强调了模型参数在评估加速行为中的作用。有趣的是，在简化过程中，模型参数中包含$β$（边界项系数）的术语消失。标量扰动已提出以显示模型的稳定性。
In this paper, we have explored the field equations of $f(T,B)$ gravity and determined the dynamical parameters with the hyperbolic function of Hubble parameter. The accelerating behavior has been observed and the behavior of equation of state parameter indicates $ΛCDM$ model at late time. The role of model parameters in assessing the accelerating behavior has been emphasized. Interestingly the term containing $β$, the coefficient of boundary term, in the model parameter vanishes during the simplification. The scalar perturbation has been presented to show the stability of the model.
