Deformations of GR and BH thermodynamics (2016)
Journal Article
Krasnov, K. (2016). Deformations of GR and BH thermodynamics. Classical and Quantum Gravity, 33(15), 1-17. https://doi.org/10.1088/0264-9381/33/15/155012

In four space–time dimensions General Relativity can be non-trivially deformed. Deformed theories continue to describe two propagating degrees of freedom, as GR. We study Euclidean black hole thermodynamics of these deformations. We use the recently... Read More about Deformations of GR and BH thermodynamics.
