利用Ricci流构造Lifshitz空间

Constructing Lifshitz spaces using the Ricci flow

R. Cartas-Fuentevilla, A. Herrera-Aguilar, J. A. Herrera-Mendoza

摘要:

本文利用Ricci流方程证明了,从度量的一般性分析出发,我们可以构造两种Lifshitz空间,其中:(a)临界指数与时空的空间维数一致,因此采用离散值;(b)临界指数是连续的和任意的。这些结果表明,Lifshitz空间是Ricci流方程的精确解。此外,我们发现,里奇流演变到一个单一的不动点,这两种情况下,这符合平坦的时空。

英文摘要:

In this work we make use of the Ricci flow equations to show that, by starting from a general ansatz for the metric, we can construct two kinds of Lifshitz spaces in which: (a) the critical exponent coincides with the spatial dimension of the spacetime and therefore adopts discrete values, and (b) the critical exponent is continuous and arbitrary. These results show that Lifshitz spaces are exact solutions to the Ricci flow equations. Moreover, we found that the Ricci flow evolves towards a single fixed point for both cases which coincides with the flat spacetime.
