On the Gravitational Wave in de Sitter Spacetime
Liao Liu
For there is always a wrong sign in the mass of graviton in the so-called perturbation expansion approximation of both Minkowski and de Sitter spacetimes, the existence of gravitat…

Could the Gravitons Have Rest Masses?
Liao Liu, Zheng Zhao
If the cosmological constant can not be neglected, we will show in this short report, that graviton should have a rest mass different from…

The statistic thermodynamical entropy of de Sitter space and it's 1-loop correction
Bo-Bo Wang, Liao Liu
From the partition function of canonical ensemble we derive the entropy of the de Sitter space by anti-Wick rotation. And then from the one-loop bubble created from…
