论文摘要

电触电理论是根据度量的四分法和与扭转的平坦联系来描述的。在本文中,我们在修饰的触电理论中研究球形对称性,该理论基于从扭转的不可还原部分构成的五个可能标量的任意功能。该理论是对所谓的新一般相对论理论的概括。我们发现,在球形对称性中,只有两个标量与零不同,我们在分析上求解相应的场方程,以获取共形远程平行性重力,然后在schwarzschild几何形状周围触及扰动,以围绕GR围绕GR。最后,我们从诸如光子球,近调偏移,shapiro延迟和光偏转的扰动溶液中计算现象学效应。我们发现他们对标准GR贡献及其对三个模型参数的依赖性的对应器校正。

Teleparallel theories of gravity are described in terms of the tetrad of a metric and a flat connection with torsion. In this paper, we study spherical symmetry in a modified teleparallel theory of gravity which is based on an arbitrary function of the five possible scalars constructed from the irreducible parts of torsion. This theory is a generalisation of the so-called New General Relativity theory. We find that only two scalars are different to zero in spherical symmetry and we solve the corresponding field equations analytically for conformal Teleparallel gravity, and then perturbatively around Schwarzschild geometry for the general perturbative theory around GR. Finally, we compute phenomenological effects from the perturbed solutions such as the photon sphere, perihelion shift, Shapiro delay, and the light deflection. We find their correspondent correction to the standard GR contribution and their dependence on the three model parameters.
