Effective Stringy Description of Schwarzschild Black Holes
Kirill Krasnov, Sergey N. Solodukhin
We start by pointing out that certain Riemann surfaces appear rather naturally in the context of wave equations in the black hole background. For a given black hole there are two c…
Twistors, CFT and Holography
Kirill Krasnov
According to one of many equivalent definitions of twistors a (null) twistor is a null geodesic in Minkowski spacetime. Null geodesics can intersect at points (events). The idea of…
Holography and Riemann Surfaces
Kirill Krasnov
We study holography for asymptotically AdS spaces with an arbitrary genus compact Riemann surface as the conformal boundary. Such spaces can be constructed from the Euclidean AdS_3…
BF Description of Higher-Dimensional Gravity Theories
L. Freidel, K. Krasnov, R. Puzio
It is well known that, in the first-order formalism, pure three-dimensional gravity is just the BF theory. Similarly, four-dimensional general relativity can be formulated as BF th…
