共形遥平行理论与Weyl几何

Conformal Teleparallel Theories and Weyl Geometry

J. B. Formiga

摘要:

尽管广义相对论(GR)已经非常成功,但许多替代的引力理论已经吸引了相当数量的理论物理学家的注意。在这些理论中,我们有共形对称的理论。在这里,使用外尔几何来处理共形telepallel重力非常详细的审查。作为应用,建立了一个等价于广义相对论远程并行等价模型(TEGR),并且在非对称同态、局部洛伦兹变换(LLT)和Weyl变换(WT)下保持不变的模型.得到了一些$pp$波解、球对称解和宇宙学解。事实证明,这类可能的解决方案比TEGR更广泛。此外,还计算和分析了宇宙的总能量和引力能。

英文摘要:

Despite the fact that General Relativity (GR) has been very successful, many alternative theories of gravity have attracted the attention of a significant number of theoretical physicists. Among these theories, we have theories with conformal symmetry. Here, the use of Weyl geometry to deal with conformal teleparallel gravity is reviewed in great detail. As an application, a model that can be set to be equivalent to the Teleparallel Equivalent of General Relativity (TEGR) and is invariant under diffeomorphisms, local Lorentz transformations (LLT) and Weyl transformations (WT) is created. Some $pp$-wave, spherically symmetric and cosmological solutions are obtained. It turns out that the class of possibles solutions is wider than that of TEGR. In addition, the total and the gravitational energies of the universe are calculated and analyzed.
