From GR to STG -- Inheritance and development of Einstein's heritages
Jianbo Lu, Yongxin Guo, Guoying Chee
A review of General Relativity, Teleparallel Gravity, and Symmetric Teleparallel gravity is given in this paper. By comparing these theories some conclusions are obtained. It is ar…
Conditions and instability in gravity with non-minimal coupling between matter and geometry
Jun Wang, Ya-Bo Wu, Yong-Xin Guo +3
In this paper on the basis of the generalized gravity model with arbitrary coupling between geometry and matter, four classes of gravity models with non minimal coupl…
Energy Conditions and Stability in generalized gravity with arbitrary coupling between matter and geometry
Jun Wang, Ya-Bo Wu, Yong-Xin Guo +2
The energy conditions and the Dolgov-Kawasaki criterion in generalized gravity with arbitrary coupling between matter and geometry are derived in this paper, which are quite…
Torsion and accelerating expansion of the universe in quadratic gravitation
Guoying Chee, Yongxin Guo
Several exact cosmological solutions of a metric-affine theory of gravity with two torsion functions are presented. These solutions give a essentially different explanation from th…
A exact de Sitter cosmological solution of quadratic gravitation with torsion
Guo-Ying Qi, Yongxin Guo
A exact de Sitter-like cosmological solution of quadratic gravitation with torsion has been found. In the limit of constant energy and pressure, it becomes a exact de Sitter spacet…
Decomposition of Almost Poisson Structure of Non-Self-Adjoint Dynamical Systems
Yongxin Guo, Chang Liu, Shixing Liu +1
Non-self-adjoint dynamical systems, e.g., nonholonomic systems, can admit an almost Poisson structure, which is formulated by a kind of Poisson bracket satisfying the usual propert…
