Hidden Symmetries for Ellipsoid–Solitonic Deformations of Kerr–Sen Black Holes and Quantum Anomalies
We prove the existence of hidden symmetries in the general relativity theory defined by exact solutions with generic off–diagonal metrics, nonholonomic (non–integrable) constraints, and deformations of the frame and linear connection structure. A special role in characterization of such spacetimes is played by the corresponding nonholonomic generalizations of Stackel–Killing and Killing–Yano te...
متن کاملNonthermal nature of extremal Kerr black holes
Liberati, Rothman and Sonego have recently showed that objects collapsing into extremal Reissner-Nordström black holes do not behave as thermal objects at any time in their history. In particular, a temperature, and hence thermodynamic entropy, are undefined for them. I demonstrate that the analysis goes through essentially unchanged for bodies collapsing into extremal Kerr black holes. PACS: 0...
متن کاملNotes on Five-dimensional Kerr Black Holes
The geometry of five-dimensional Kerr black holes is discussed based on geodesics and Weyl curvatures. Kerr-Star space, Star-Kerr space and Kruskal space are naturally introduced by using special null geodesics. We show that the geodesics of AdS Kerr black hole are integrable, which generalizes the result of Frolov and Stojkovic. We also show that five-dimensional AdS Kerr black holes are isosp...
متن کاملStrings in Kerr-newmann Black Holes
We study the evolution of strings in the equatorial plane of a Kerr-Newmann black hole. Writing the equations of motion and the constraints resulting from Hamilton’s principle, three classes of exact solutions are presented, for a closed string, encircling the black-hole. They all depend on two arbitrary, integration functions and two constants. A process for extracting energy is examined for t...
متن کاملThermodynamics of Noncommutative Quantum Kerr Black Holes
The thermodynamic formalism for rotating black holes, characterized by noncommutative and quantum corrections, is constructed. From a fundamental thermodynamic relation, the equations of state and thermodynamic response functions are explicitly given, and the effect of noncommutativity and quantum correction is discussed. It is shown that the well-known divergence exhibited in specific heat is ...
