摘要:

本文研究了对称远平行引力(即f(Q)引力理论)背景下精确的渐近平坦虫洞解。由于修正引力理论提供了新的场方程,我们利用修正场方程分析了一些可能的虫洞解。考虑了四种不同形式的f(Q)函数,然后利用一些不同的状态方程计算了形状函数。此外,我们还在这些模型中使用了幂律形状函数,从而得到了渐近正压状态方程。文中还讨论了这些解的一些物理和数学性质,例如能量条件和边界条件。

英文摘要:

In this paper, exact asymptotically flat wormhole solutions in the context of symmetric teleparallel gravity, i.e., $f(Q)$ theory of gravity, are investigated. Since modified theories of gravity provide new field equations, we have analyzed some possible wormhole solutions by using modified field equations. Four different forms of the $f(Q)$ function are considered then the shape function is calculated with some different equations of state. Also we have used a power-law shape function with these models, which lead to an asymptotically barotropic equation of state. Some physical and mathematical properties of the solutions, like energy conditions and boundary conditions, are addressed .
