Zusammenfassung:In the present article, models of traversable wormholes within the f ( R , T ) modified gravity theory, where R is the Ricci scalar and T is the trace of the energy-momentum tensor, are investigated. We have presented some wormhole models, which are formulated from various hypothesis for their matter content, i.e. various relations for their lateral and radial pressure components. The solutions found for the shape functions of the wormholes produced complies with the required metric conditions. The validity of solution is examined by exploring null, strong and dominant energy conditions. It is concluded that the normal matter in the throat may pursue the energy conditions, and it is the higher-order curvature terms, termed as the gravitational field, that supports the non-standard geometries of wormholes in the context of modified gravity.
