In this paper, we examine the embedded wormhole solutions in the modified f(,T) theory of gravity, where T denotes the trace of the energy–momentum tensor and is the Ricci scalar. We derive the embedded class-1 solutions by considering spherically symmetric static spacetime. The shape function is calculated in the framework of embedded class-1 spacetime. It is necessary to mention here that the calculated shape function can be used in other modified theories of gravity. We explore the feasible solutions for the specific model of f(,T) theory of gravity. Energy conditions have been explored using the approach mentioned above. Conclusively, we find that obtained wormhole solutions are acceptable, as the null energy condition is violated in the specific region.

通过嵌入方法在 ℛ + βℛ2 重力与物质耦合中的虫洞解决方案

在本文中,我们研究了修改后的嵌入式虫洞解决方案F(,)引力理论,其中表示能量-动量张量的轨迹,并且是 Ricci 标量。我们通过考虑球对称静态时空推导出嵌入的 1 类解决方案。形函数是在嵌入式 1 类时空框架下计算的。这里有必要提一下,计算出的形函数可以用于其他修正的重力理论。我们探索针对特定模型的可行解决方案F(,)引力理论。已经使用上述方法探索了能量条件。最后,我们发现获得的虫洞解是可以接受的,因为在特定区域中违反了零能量条件。
