On one-loop renormalization of black-hole entropy
Dmitri V. Fursaev, Sergey N. Solodukhin
One-loop divergences appearing in the entropy of a quantum black hole are proven to be completely eliminated by the standard renormalization of both the gravitational constant and…
On "Non-Geometric" Contribution To The Entropy Of Black Hole Due To Quantum Corrections
S. N. Solodukhin
The quantum corrections to the entropy of charged black holes are calculated. The Reissner-Nordstrem and dilaton black holes are considered. The appearance of logarithmically diver…
The Conical Singularity And Quantum Corrections To Entropy Of Black Hole
S. N. Solodukhin
For general finite temperature different from the Hawking one there appears a well known conical singularity in the Euclidean classical solution of gravitational equations. The met…
On Higher Derivative Gravity in Two Dimensions
S. N. Solodukhin
The 2D gravity described by the action which is an arbitrary function of the scalar curvature is considered. The classical vacuum solutions are analyzed. The one-loop renorm…
Exact Solution of 2D Poincare Gravity Coupled to Fermion Matter
S. N. Solodukhin
The 2D model of gravity with zweibeins and the Lorentz connection one-form as independent gravitational variables coupled to 2d massless Dirac matter is consi…
On Exact Integrability of 2D Poincare Gravity
S. N. Solodukhin
We consider the 2D Poincaré gravity and show its exact integrability. The choice of the gauge is discussed. The Euclidean solutions on compact closed differential manifolds are stu…
