Abstract We study an interesting alternative of modified gravity theory, namely, the unimodular f ( R , T ) in which is Ricci scalar and trace stress–energy tensor. viability model by using energy conditions. discuss strong, weak, null dominant conditions terms deceleration, jerk snap parameters. investigate for reconstructed models give some constraints on parametric space model. observe that ...

In this manuscript, we construct generalized Ellis-Bronnikov wormholes in the context of $f(R)$ modified theories gravity. We consider that matter driving wormhole satisfies energy conditions so it is effective energy-momentum tensor containing higher-order derivatives curvature terms violate null condition. Thus, gravitational fluid interpreted by to represent geometries and fundamentally diff...
