The first law of black hole mechanics in conformal Einstein-Power-Yang-Mills theory
Xiaokai He, Xiaoning Wu, Naqing Xie
In the framework of the Iyer-Wald formalism, the first law of black hole mechanics is examined within the context of conformal Einstein-power-Yang-Mills (CEPYM) theory. By comparin…

The total geodesic curvature and the -dimensional hyperbolic mass
Xiaokai He, Xiaoning Wu, Naqing Xie
In this paper, we derive a novel geometric inequality involving the total geodesic curvature, serving as an analogue of the Brown-York mass in the setting of -dimensional gr…

Bondi Mass, Memory Effect and Balance Law of Polyhomogeneous Spacetime
Xiaokai He, Xiaoning Wu, Naqing Xie
Spacetimes with metrics admitting an expansion in terms of a combination of powers of 1/r and ln r are known as polyhomogeneous spacetimes. The asymptotic behaviour of the Newman-P…
