Mechanics and Newton-Cartan-Like Gravity on the Newton-Hooke Space-time
Yu Tian, Han-Ying Guo, Chao-Guang Huang +2
We focus on the dynamical aspects of Newton-Hooke space-time mainly from the viewpoint of geometric contraction of the de Sitter spacetime. We first discuss the Newto…
The Generalized Liouville's Theorems via Euler-Lagrange Cohomology Groups on Symplectic Manifold
Han-Ying Guo, Jianzhong Pan, Bin Zhou
Based on the Euler-Lagrange cohomology groups on symplectic manifold , their properties and a kind o…
Temperature at Horizon in de Sitter Spacetime
Han-Ying Guo, Chao-Guang Huang, Bin Zhou
It is found that there is no period in the imaginary Beltrami-time of the de Sitter spacetime with Beltrami metric and that the `surface-gravity' in view of inertial observers in d…
Newton-Hooke Limit of Beltrami-de Sitter Spacetime, Principles of Galilei-Hooke's Relativity and Postulate on Newton-Hooke Universal Time
Chao-Guang Huang, Han-Ying Guo, Yu Tian +2
Based on the Beltrami-de Sitter spacetime, we present the Newton-Hooke model under the Newton-Hooke contraction of the spacetime with respect to the transformation group, alg…
