摘要:

本文以挠率作为描述引力的几何对象,根据等效原理,研究了广义遥平行引力模型下的四维带电静态黑洞。作为一个有启发性的想法,我们引入了一组非对角四元组,并推导出完整的非线性微分方程组。我们证明了普通史瓦西规范只适用于线性f(T)情形。我们重新获得了f(T)线性情形的Reissner-Nordstrom-deSitter(或RN-AdS)解,并对两个非线性模型进行了参数宇宙学重建.我们还详细研究了一种类型的不去定理的框架下,这种修改的远程平行引力。

英文摘要:

In this paper we investigate charged static black holes in 4D for generalized teleparallel models of gravity, based on torsion as the geometric object for describing gravity according to the equivalence principle. As a motivated idea, we introduce a set of non-diagonal tetrads and derive the full system of non linear differential equations. We prove that the common Schwarzschild gauge is applicable only when we study linear f(T) case. We reobtain the Reissner-Nordstrom-de Sitter (or RN-AdS) solution for the linear case of f(T) and perform a parametric cosmological reconstruction for two nonlinear models. We also study in detail a type of the no-go theorem in the framework of this modified teleparallel gravity.
