与Reissner-Nordström解相似的共形引力理论的比较

Comparison of conformal gravitation theories by solutions analogous to Reissner-Nordström ones

M. V. Gorbatenko, S. Yu. Sedov

摘要:

对于有质量和电荷的物体,给出了一种共形不变引力理论(共形几何动力学- CG)的精确解。该解类似于广义相对论中的Reissner-Nordström解。它的类似解决方案早些时候由Manneland和Kazanas为保角不变引力理论的不同版本- Weyl Conformal Gravitation Theory(Weyl CGt)提出。类似的解决方案不符合。与类似的解决方案的一致性问题进行了讨论。得出了只有由共形几何动力学(CG)方程产生的相似解才对应于电动力学方程的结论。

英文摘要:

An exact solution was produced for one of the versions of conformal -invariant gravitation theories (conformal geometrodynamics - CG) for the body with a mass and an electric charge. The solution is analogous to the Reissner-Nordström solution in the general relativity theory. Its similar solution was earlier produced by Mannheit and Kazanas for the different version of the conformal-invariant gravitation theory -- Weyl conformal gravitation theory (Weyl CGt). Similar solutions do not comply. Issues of conformity with regard to the similar solutions are discussed. A conclusion is made that only the similar solution produced from conformal geometrodynamics (CG) equations corresponds to electrodynamic equations.
