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
We consider a Jordan domain diffeomorphic to a closed two-dimensional disk with a smooth boundary. Assuming the Gauss curvature of the domain has a negative lower bound, the Gauss-…

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…
