چکیده
We consider the f(R,T) theory of gravity, in which gravitational Lagrangian is given by an arbitrary function Ricci scalar and trace energy–momentum tensor, to study static spherically symmetric wormhole geometries sustained matter sources with isotropic pressure. According restrictions on geometries, we carefully adopt different strategies construct solutions properties characteristics wormholes. Using utterly general procedure, provide several examples wormholes threading throat satisfies all energy conditions discuss mechanisms for finding them. Finally, postulate a smooth transformation simplifying nonlinear field equations have more consistent results than other ones conclude that can be viewed as specific exact without exotic matter.

The null energy condition in dynamic wormholes
We extend previous proofs that violations of the null energy condition (NEC) are a generic and universal feature of traversable wormholes to completely non-symmetric time-dependent wormholes. We show that the analysis can be phrased purely in terms of local geometry at and near the wormhole throat, and do not have to make any technical assumptions about asymptotic flatness or other global prope...
متن کاملGeneral Dynamic Wormholes and Violation of the Null Energy Condition
Although wormholes can be treated as topological objects in spacetime and from a global point-of-view, a precise definition of what a wormhole throat is and where it is located can be developed and treated entirely in terms of local geometry. This has the advantage of being free from unnecesary technical assumptions about asymptotic flatness, and other global properties of the spacetime contain...

متن کاملTraversable wormholes with arbitrarily small energy condition violations.
Traversable wormholes necessarily require violations of the averaged null energy condition, this being the definition of "exotic matter." However, the theorems which guarantee the energy condition violation are remarkably silent when it comes to making quantitative statements regarding the "total amount" of energy condition violating matter in the spacetime. We develop a suitable measure for qu...
متن کاملStrong energy condition in R+R2 gravity.
In this paper, we study Raychaudhuri's equation in the background of R + βR 2 gravity with a phenomenological matter (ρ ∝ a(t) −n). We conclude that even though the Strong Energy Condition (S.E.C.) for Einstein's gravity, which guarantees singularity, is n ≥ 2 for ρ ∝ a(t) −n , a perturbative analysis of Raychaudhuri's equation in the background of R+βR 2 gravity reveals that the big bang singu...
