论文摘要
在这项工作中，考虑了$ f（r）$ gravity在功能$ f（r）= r+αr^n $的研究中的研究，其中$α$和$ n $是任意常数。 Samanta等人建议的形状函数$ b（r）= \ frac {r} {\ exp（r-r_0）} $。 \ cite {godani1}被考虑。讨论了相对于恒定和可变的红移功能的能量条件，并研究了虫洞溶液的存在而没有外来物质。
In this work, the study of traversable wormholes in $f(R)$ gravity with the function $f(R)=R+αR^n$, where $α$ and $n$ are arbitrary constants, is taken into account. The shape function $b(r)=\frac{r}{\exp(r-r_0)}$, proposed by Samanta et al. \cite{godani1}, is considered. The energy conditions with respect to both constant and variable redshift functions are discussed and the existence of wormhole solutions without presence of exotic matter is investigated.
