Noether Currents of Charged Spherical Black Holes
Michael C. Ashworth Sean A. Hayward
We calculate the Noether currents and charges for Einstein-Maxwell theory using a version of the Wald approach. In spherical symmetry, the choice of time can be taken as the Kodama…

Boundary Terms and Noether Current of Sphereical Black Holes
Michael C. Ashworth, Sean A. Hayward
We consider two proposals for defining black hole entropy in spherical symmetry, where the horizon is defined locally as a trapping horizon. The first case, boundary terms in a dua…

Dynamic black-hole entropy
Sean A. Hayward, Shinji Mukohyama, M. C. Ashworth
We consider two non-statistical definitions of entropy for dynamic (non-stationary) black holes in spherical symmetry. The first is analogous to the original Clausius definition of…
