Exact solutions of embedding the four-dimensional perfect fluid in a five- or higher-dimensional Einstein spacetime and the cosmological interpretations
Jie Ren, Xin-He Meng, Liu Zhao
We investigate an exact solution that describes the embedding of the four-dimensional (4D) perfect fluid in a five-dimensional (5D) Einstein spacetime. The effective metric of the…

Hamiltonian formalism in Friedmann cosmology and its quantization
Jie Ren, Xin-He Meng, Liu Zhao
We propose a Hamiltonian formalism for a generalized Friedmann-Roberson-Walker cosmology model in the presence of both a variable equation of state (EOS) parameter and a var…

Conservative Currents of Boundary Charges in Gravity
Sze-Shiang Feng, Bin Wang, Xin-He Meng
The boundary charges which constitute the Virasoro algebra in 2+1 dimensional anti-de Sitter gravity are derived by way of Noether theorem and diffeomorphic invariance. It shows th…
