摘      要：This work provides some feasible regions for the existence of traversable wormhole geometries in modified f ( 𝒢 , T ) gravity. For this purpose, three different matter contents have been studied with special emphasis on anisotropic fluid by considering a specific f ( 𝒢 , T ) gravity power law model. It has been shown that the null energy conditions for the effective energy–momentum tensor are widely violated for the ordinary matter content. However, some small feasible regions to support the wormhole solutions have been noted. Furthermore, the stability of the anisotropic feasible regions for the wormhole solutions has been discussed. It is concluded that the wormhole geometries threaded by the ordinary matter actually exist and are well stable in f ( 𝒢 , T ) gravity.
