F. Darabi, M. Golmohammadi, A. Rezaei-Aghdam

摘要:

在本文中,我们使用Hojman对称性方法来寻找新的$(2+1)$ -维$f(R)$重力解,在比较Noether对称性方法。在Hojman对称性矢量$X=R$的特殊情况下,我们恢复了$(2+1)$维BTZ黑洞和广义$(2+1)$维BTZ黑洞的Noether对称性解,有趣的是宇宙学常数作为Hojman对称性的直接表示.

英文摘要:

In this paper, we use the Hojman symmetry approach to find new $(2+1)$-dimensional $f(R)$ gravity solutions, in comparison to Noether symmetry approach. In the special case of Hojman symmetry vector $X=R$, we recover $(2+1)$-dimensional BTZ black hole and generalized $(2+1)$-dimensional BTZ black hole solutions, obtained by Noether symmetry approach, and the interesting point is that the cosmological constant is appeared as the direct manifestation of Hojman symmetry.
