Intrinsic time gravity and the Lichnerowicz-York equation
Niall Ó Murchadha, Chopin Soo, Hoi-Lai Yu
We investigate the effect on the Hamiltonian structure of general relativity of choosing an intrinsic time to fix the time slicing. 3-covariance with momentum constraint is maintai…

Affine group representation formalism for four dimensional, Lorentzian, quantum gravity
Chou Ching-Yi, Eyo Ita, Chopin Soo
Within the context of the Ashtekar variables, the Hamiltonian constraint of four-dimensional pure General Relativity with cosmological constant, , is reexpressed as an affine al…
