在华罗庚教授的建议下，陆启铿、郭汉英，邹振隆七十年代发展了de Sitter与反de Sitter狭义相对论。我们在这个框架下，构造了Schwarzschild黑洞解。

In B. Pourhassan and H. Farahani，Thermodynamics of Higher Order Entropy Corrected Schwarzschild-Beltrami-de Sitter Black Hole (arXiv1701.0865)，In this paper we would like to use this result to study modified thermodynamics of Schwarzschild- 3 Beltrami-de Sitter black hole [33] which is indeed an unstable dynamical black hole and obtained by introducing inertial Beltrami coordinates to traditional non-inertial Schwarzschild-de Sitter metric.

我们提出几何宇宙学常数的概念，将宇宙学常数与de Sitter时空的参数分开。这些想法引起了一些宇宙学家的兴趣。
