标题： Cosmological sector for localized mass and spin in 2+1 dimensional topologically massive gravity

摘要： 宇宙学部分的完整非线性拓扑质量引力（TMG）是针对质量为$m$和自旋为$\sigma$的局域源得到的，除此之外还包括之前获得的渐近自旋锥形平直部分。在源外部但靠近源的小区域内，度规类似于自旋锥形平直度规，但我们发现质量$m$会产生一个负的缺角$3m$，与$m$相反。此外，在极限$\mu \to \infty$下无法恢复纯爱因斯坦引力的结果，这与平直部分不同。 显示英文摘要

摘要： The cosmological sector to the full non-linear topologically massive gravity (TMG) is obtained for localized sources of mass $m$ and spin $\sigma$ besides the asymptotically spinning conical flat sector previously obtained. In a small region near but outside the sources, the metric resembles the spinning conical flat metric, but we find that the mass $m$ creates a negative deficit angle of $3m$ as opposed to $m$. Furthermore, it is not possible to recover the results of pure Einstein gravity in the limit $\mu \to \infty$ unlike the flat sector.
