Generalized Formalism in Gauge-Invariant Gravitational Perturbations
Rong-Gen Cai, Li-Ming Cao
By use of the gauge-invariant variables proposed by Kodama and Ishibashi, we obtain the most general perturbation equations in the -dimensional spacetime with a warped produ…
On dRGT massive gravity with degenerate reference metrics
Li-Ming Cao, Yuxuan Peng, Yun-Long Zhang
In dRGT massive gravity, to get the equations of motion, the square root tensor is assumed to be invertible in the variation of the action. However, this condition can not be fulfi…
The instability of the inner horizon of the quantum-corrected black hole
Li-Ming Cao, Long-Yue Li, Liang-Bi Wu +1
We analyse the stability of the inner horizon of the quantum-corrected black hole which is proposed in loop quantum gravity as the exterior of the quantum Oppenheimer-Snyder and Sw…
Quasinormal modes of tensor perturbation in Kaluza-Klein black hole for Einstein-Gauss-Bonnet gravity
Li-Ming Cao, Liang-Bi Wu, Yaqi Zhao +1
In Einstein-Gauss-Bonnet gravity, we study the quasi-normal modes (QNMs) of the tensor perturbation for the so-called Maeda-Dadhich black hole which locally has a topology $\mathca…
Generalized Vaidya Spacetime in Lovelock Gravity and Thermodynamics on Apparent Horizon
Rong-Gen Cai, Li-Ming Cao, Ya-Peng Hu +1
We present a kind of generalized Vaidya solutions in a generic Lovelock gravity. This solution generalizes the simple case in Gauss-Bonnet gravity reported recently by some authors…
Decay criteria for asymptotic freedom in plane gravitational waves
Qi-Liang Zhao, Li-Ming Cao
We investigate when plane-wave memory admits standard outgoing free data beyond the idealized sandwich-wave approximation. For a Brinkmann plane wave with profile , the commo…
