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…
