Journal ArticleDOI
Geometry of Black Hole Thermodynamics
TL;DR: In this article, the Riemannian geometry of the Hessian of the entropy function was studied for some families of black holes, including the BTZ and Reissner-Nordstrom black holes.
Journal ArticleDOI
Geometry of higher-dimensional black hole thermodynamics
Jan E. Åman,Narit Pidokrajt +1 more
TL;DR: In this paper, the authors investigated the statistical mechanics of black holes using an information geometric approach (Ruppeiner and Weinhold geometry) and derived a flatness theorem based on the scaling property of the black holes, which proves to be useful in many cases.
Journal ArticleDOI
Geometry of black hole thermodynamics
TL;DR: In this paper, the Riemannian geometry of the Hessian of the entropy function was studied for some families of black holes, and the curvature singularities for the Reissner-Nordstrom-anti-de Sitter and Kerr black holes were established.
Journal ArticleDOI
Flat Information Geometries in Black Hole Thermodynamics
TL;DR: The Hessian of either the entropy or the energy function can be regarded as a metric on a Gibbs surface as discussed by the authors, and the Hessian can be viewed as a function of the number of asymptotically flat black holes.
Journal ArticleDOI
A computer-aided complete classification of geometries in general relativity. First results
Jan E. Åman,Anders Karlhede +1 more
TL;DR: In this paper, a computer-aided classification of geometries in terms of the curvature tensor and its covariant derivatives is presented, which extends the Petrov classification to a complete classification of the local geometry and the dimensions of the group of motions and its isotropy subgroup are obtained.
