Traversable wormholes in R+αR${}^n$ gravity

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)=$\frac{r}{exp\left(r\text{â}\text{ˆ}\text{’}{r}_0\right)}$, proposed by Samanta et al. (arXiv:1811.06834v1 [gr-qc], 2018), 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.
