Discovering the Kerr and Kerr-Schild metrics
The story of this metric begins with a paper by Alexei Zinovievich Petrov (1954) where the simultaneous invariants and canonical forms for the metric and conformal tensor are calculated at a general point in an Einstein space. This paper took a while to be appreciated in the West, probably because the Kazan State University journal was not readily available, but Felix Pirani (1957) used it as t...
متن کاملKerr-Bolt Spacetimes and Kerr/CFT Correspondence
We investigate the recently proposed Kerr/CFT correspondence in the context of rotating spacetimes with a NUT twist. The Kerr/CFT correspondence states that the near-horizon states of an extremal four (or higher) dimensional black hole could be identified with a certain chiral conformal field theory. The corresponding Virasoro algebra is generated with a class of diffeomorphism which preserves ...
متن کاملSpatial solitons in Kerr and Kerr-like media
This is a review paper of basic knowledge and recent advances in the area of spatial solitons in Kerr and Kerr-like media. We consider spatial bright and dark solitons, sol-itons in waveguide geometries, optical bullets, vortex solitons and, brie¯y, dissipative cases. In our treatment, we use a Hamiltonian approach when considering stability issues.
متن کاملCollective drawing
This paper is referred to the experiences run at Iuav since 2004 in the framework of the EU-FSE founded Courses of Collaborative Composition. In these courses we built up some work/game thought as meaning of a distance collaborative game. Rally around these games, we delivered specific knowledge and portions of technical knowledge referred to the issue of formal structure, shape grammar, and co...
متن کاملThe Kerr/CFT Correspondence
Quantum gravity in the region very near the horizon of an extreme Kerr black hole (whose angular momentum and mass are related by J = GM2) is considered. It is shown that consistent boundary conditions exist, for which the asymptotic symmetry generators form one copy of the Virasoro algebra with central charge cL = 12J ~ . This implies that the near-horizon quantum states can be identified with...
