相对论宇宙学中结构形成的拉格朗日理论III:任意阶的引力电微扰和解方案

Alexandre Alles, Thomas Buchert, Fosca Al Roumi, Alexander Wiegand

摘要:

研究了牛顿拉格朗日微扰理论的相对论推广。在以前的工作中,一阶迹的解决方案,所产生的空间投影的Weyl张量的引力电的一部分,与扩展和应用程序一起访问非微扰制度。我们在这里提供建设规则,以获得从牛顿的解决方案的相对论性的解决方案,我们给完整的扰动和解决方案,在任何顺序的扰动的引力电类。通过构造,这些方案推广了牛顿拉格朗日摄动理论的完整解族。

英文摘要:

The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the first-order trace solutions that are generated by the spatially projected gravitoelectric part of the Weyl tensor were given together with extensions and applications for accessing the nonperturbative regime. We furnish here construction rules to obtain from Newtonian solutions the gravitoelectric class of relativistic solutions, for which we give the complete perturbation and solution schemes at any order of the perturbations. By construction, these schemes generalize the complete hierarchy of solutions of the Newtonian Lagrangian perturbation theory.
