Higher derivative corrections to Kerr-AdS black hole thermodynamics
Wei Guo, Xiyao Guo, Xin Lan +2
Instead of the much more involved covariant counterterm method, we apply the well justified background subtraction method to calculate the first order corrections to Kerr-AdS black…

Background subtraction method is not only much simpler, but also as applicable as covariant counterterm method
Wei Guo, Xiyao Guo, Xin Lan +2
As the criterion for the applicability of the background subtraction method, not only the finiteness condition of the resulting Hamiltonian but also the condition for the validity…

Equivalence of Noether charge and Hilbert action boundary term formulas for the black hole entropy in gravity theory
Wei Guo, Xiyao Guo, Mingfeng Li +2
By working with the covariant phase space formalism, we have shown that not only can the Hamiltonian conjugate to a Killing vector field be expressed as the sum of the associa…
