论文摘要
这篇综述的目的是讨论基于D维世界中具有较高衍生物的重力获得结果的方法。我们考虑了以下方式:(1)将标量张量的重力减小,(2)运动方程的直接解,(3)在系统中存在小参数的情况下近似方程的推导,以及(4)测试函数的方法。提出了一些应用程序来说明每种方法。未来理论的两个必要要素的统一也牢记 - 额外的维度和重力的扩展形式。
The aim of this review is to discuss the ways to obtain results based on gravity with higher derivatives in D-dimensional world. We considered the following ways: (1) reduction to scalar tensor gravity, (2) direct solution of the equations of motion, (3) derivation of approximate equations in the presence of a small parameter in the system, and (4) the method of test functions. Some applications are presented to illustrate each method. The unification of two necessary elements of a future theory is also kept in mind - the extra dimensions and the extended form of the gravity.
