Gravitational Entropy
Sangmin Choi, Malcolm J. Perry
We formulate the classical gravitational entropy of a horizon as a Noether charge that does not require the notion of a temperature, and which is applicable to horizons that are no…

Quantization of Black Hole Entropy for Black Holes in Subtracted Geometry
Mirjam Cvetic, Malcolm J. Perry
We carefully examine the exact analytic spectrum of quasinormal modes of general black holes in the so-called subtracted geometry of maximally supersymmetric supergravity. These bl…
