论文摘要
我们研究了被称为regge-teitelboim方法的修饰的重力理论,其中重力是由表面异位嵌入的表面动力学表示的。我们获得了与中央对称真空2+1维时空相对应的regge-teitelboim方程的一些特定解。与GR相反,这种真空时空不是平坦的,因此即使没有物质或宇宙常数,引力场也可能存在。
We study modified gravity theory known as Regge-Teitelboim approach, in which the gravity is represented by dynamics of a surface isometrically embedded in a flat bulk. We obtain some particular solutions of Regge-Teitelboim equations corresponding to a central symmetric vacuum 2+1-dimensional spacetime. In contrast with GR, this vacuum spacetime is not flat, so it is possible for the gravitational field to exist even without matter or cosmological constant.
