Talk	Oral abstract	Title	Entropy of a black hole from the semiclassical Euclidean action formulation
Co-authors	Wontae Kim, Edwin J. Son
Abstract	The entropy of the Schwarzschild-anti de Sitter black hole in the recently proposed four-dimensional critical gravity is trivial in the Euclidean action formulation, while it can be expressed by the area law in terms of the brick wall method given by 't Hooft. To resolve this discrepancy, we related the Euclidean action formulation to the brick wall method semiclassically, and show that the entropy of the black hole can be expressed by the area law even at the critical point.
