Lorentz group in gravity theories
Jianbo Lu, Yongxin Guo, G. Y. Chee
In this paper, it is argued that in gravity theories the local Lorentz group can not be considered as a gauge group in the sense of Yang-Mills theories, the Lorentz connection is n…
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…
Cosmology in symmetric teleparallel gravity and its dynamical system
Jianbo Lu, Xin Zhao, Guoying Chee
We explore an extension of the symmetric teleparallel gravity denoted the theory, by considering a function of the nonmetricity invariant as the gravitational Lagrangian…
Cosmology in Poincare gauge gravity with a pseudoscalar torsion
Jianbo Lu, Guoying Chee
A cosmology of Poincare gauge theory is developed, where several properties of universe corresponding to the cosmological equations with the pseudoscalar torsion function are inves…
A Poincare-Starobinsky-Yang-Mills type model of dark energy
Jianbo Lu, G. Y. Chee
Starting from the Poincare Gauge principle and a Starobinsky-Yang-Mills type Lagrangian a model of dark energy is developed. In order to evade any unnecessary controversy regarding…
Acceleration of the cosmic expansion induced by symmetry breaking
G. Y. Chee
It is proved that in order to obtain a model of the accelerated cosmic expansion the thing one only need to do is to add a perturbation term to the Einstein-Hilbert Lagrangian. Thi…
