A Note on the Strong Hyperbolicity of Gravity with Dynamical Shifts
Li-Ming Cao, Liang-Bi Wu
The well-posedness of the gravitational equations of gravity are studied in this paper. Three formulations of the gravity with dynamical shifts (which are all based o…
A Bound on the Rate of Bondi Mass Loss
Li-Ming Cao, Long-Yue Li, Liang-Bi Wu
To ensure the light (emitted far away from the source of gravity) can arrive at the null infinity of an asymptotically flat spacetime, it is shown that the rate of Bondi mass aspec…
On the "Einstein-Gauss-Bonnet Gravity in Four Dimension"
Li-Ming Cao, Liang-Bi Wu
To ensure the existence of a well defined linearized gravitational wave equation, we show that the spacetimes in the so-called "Einstein-Gauss-Bonnet gravity in four dimension" hav…
Hyperbolicity and Causality of Einstein-Gauss-Bonnet Gravity in Warped Product Spacetimes
Li-Ming Cao, Liang-Bi Wu
In Einstein-Gauss-Bonnet gravity, for a group of warped product spacetimes, we get a generalized master equation for the perturbation of tensor type. We show that the "effective me…
