A comparison between Jordan and Einstein frames of Brans-Dicke gravity a la loop quantum cosmology
Michal Artymowski, Yonnge Ma, Xiangdong Zhang
It is well known that the Jordan and Einstein frames are equivalent to each other in classical Brans-Dicke theory, provided that one and the same metric is employed for the physica…

Connection Dynamics for Higher Dimensional Scalar-Tensor Theories of Gravity
Yu Han, Yongge Ma, Xiangdong Zhang
The scalar-tensor theories of gravity in spacetime dimensions are studied. By doing Hamiltonian analysis, we obtain the geometrical dynamics of the theories from their Lagr…
