Publication date: Available online 10 January 2020Source: Physics of the Dark UniverseAuthor(s): Kh. Saaidi, N. NazavariAbstractIn this manuscript we consider the traversable wormhole solutions in teleparallel gravity formalism with and without Rastall constraint on perfect fluid stress–energy tensor. We have studied the isotropic and non-isotropic form of stress–energy tensor of ideal fluid which the equation of state (EoS) between density and the radial components of pressure is used. This work is done for a diagonal tetrad and we have found some geometries which could describe a traversable wormhole, but the null energy and weak energy conditions were not violated for some sets of parameters.
