摘要:

通过考虑形状函数$b(r)$和红移函数$Φ(r)$的两种不同表述,研究了对数修正的$f(R)$模型的可穿越虫洞解.计算了相应形式的能量密度$ρ$、切向压力$P_{t}$和径向压力$P_{r}$等模型参数。然后,我们研究了不同的能量条件,如零能量条件,弱能量条件,主导能量条件和强能量条件,我们考虑的情况。最后,我们用相关的图说明了模型能量满足的条件。

英文摘要:

We study the traversable wormhole solutions for a logarithmic corrected $f(R)$ model by considering two different statements of shape $b(r)$ and redshift $Φ(r)$ functions. We calculate the parameters of the model including energy density $ρ$, tangential pressure $P_{t}$ and radial pressure $P_{r}$ for the corresponding forms of the functions. Then, we investigate different energy conditions such as null energy condition, weak energy condition, dominant energy condition and strong energy condition for our considered cases. Finally, we explain the satisfactory conditions of energy of the models by related plots.
