f(T)理论中球对称的静态解

Static Solutions with Spherical Symmetry in f(T) Theories

Tower Wang

摘要:

本文研究了引力理论中几种带Maxwell项的f(T)模型的球对称静态解。为了做到这一点,我们证明了重构f(T)理论的拉格朗日量对框架的选择是敏感的,然后我们引入了一个基于共形笛卡尔坐标的特定框架。在这个特殊的框架下,给出了各种解的存在条件。我们的结果意味着只有有限的一类f(T)模型可以在这个框架中解决。对于更一般的模型,寻找球对称静态解仍然是一个开放的和具有挑战性的问题,希望在其他框架下解决。

英文摘要:

The spherically symmetric static solutions are searched for in some f(T) models of gravity theory with a Maxwell term. To do this, we demonstrate that reconstructing the Lagrangian of f(T) theories is sensitive to the choice of frame, and then we introduce a particular frame based on the conformally Cartesian coordinates. In this particular frame, the existence conditions of various solutions are presented. Our results imply that only a limited class of f(T) models can be solved in this frame. For more general models, the search for spherically symmetric static solutions is still an open and challenging problem, hopefully solvable in other frames.
