Black Hole Entropy: Off-Shell vs On-Shell
V. P. Frolov, D. V. Fursaev, A. I. Zelnikov
Different methods of calculation of quantum corrections to the thermodynamical characteristics of a black hole are discussed and compared. The relation between on-shell and off-she…
Graded Contractions of Affine Kac-Moody Algebras
Marc de Montigny
The method of graded contractions, based on the preservation of the automorphisms of finite order, is applied to the affine Kac-Moody algebras and their representations, to yield a…
Nucleon Decay in Non-Minimal Supersymmetric SO(10)
Alick L. Macpherson
Evaluation of nucleon decay modes and branching ratios in a non-minimal supersymmetric SO(10) grand unified theory is presented. The non-minimal GUT considered is the supersymmetri…
Cosmological Inflation and the Nature of Time
D. S. Salopek
Recent advances in observational cosmology are changing the way we view the nature of time. In general relativity, the freedom in choosing a time hypersurface has hampered the impl…
How to Create a 2-D Black Hole
V. Frolov, S. Hendy, A. L. Larsen
The interaction of a cosmic string with a four-dimensional stationary black hole is considered. If a part of an infinitely long string passes close to a black hole it can be captur…
How Many New Worlds Are Inside a Black Hole?
Claude Barrabès, Valeri Frolov
We propose a possible internal structure for a Schwarzschild black hole resulting from the creation of multiple de Sitter universes with lightlike boundaries when the curvature rea…
Covariant double-null dynamics: -splitting of the Einstein equations
P. R. Brady, S. Droz, W. Israel +1
The paper develops a -imbedding formalism adapted to a double foliation of spacetime by a net of two intersecting families of lightlike hypersurfaces. The formalism is two-d…
Symmetry Reductions of the Lax Pair of the Four-Dimensional Euclidean Self-Dual Yang-Mills Equations
M. Legare
The reduction by symmetry of the linear system of the self-dual Yang-Mills equations in four-dimensions under representatives of the conjugacy classes of subgroups of the connected…
The Spectrum and Confinement for the Bethe-Salpeter Equation
A. Yu. Umnikov, F. C. Khanna
The problem of calculating of the mass spectrum of the two-body Bethe-Salpeter equation is studied with no reduction to the three-dimensional ("quasipotential") equation. The metho…
Two observers calculate the trace anomaly
A. Z. Capri, M. Kobayashi, D. J. Lamb
We adapt a calculation due to Massacand and Schmid to the coordinate independent definition of time and vacuum given by Capri and Roy in order to compute the trace anomaly for a ma…
Mass Inflation in a Rotating Charged Black Hole
Alfio Bonanno
The structure of the Cauchy horizon of a charged rotating black hole is analyzed under the combined effect of an ingoing and outgoing flux of gravitational waves. In particular, by…
Quantum Cosmology Lectures
Don N. Page
Quantum cosmology is the quantum theory of the entire universe. Although strange at first sight, it is appropriate because (1) our world appears to be fundamentally quantum, (2) th…
Aspects of Quantum Cosmology
Don N. Page
Quantum mechanics may be formulated as SENSIBLE QUANTUM MECHANICS (SQM) so that it contains nothing probabilistic, except, in a certain frequency sense, conscious perceptions. Sets…
Attaching Theories of Consciousness to Bohmian Quantum Mechanics
Don N. Page
The de Broglie-Bohm theory of quantum mechanics (here simply called Bohmian Mechanics or BM) [1-10] is an augmentation of ``bare'' quantum mechanics (the bare theory being given by…
Relativistic Calculations for Photonuclear Reactions (II). Nonrelativistic reductions and nuclear medium effects
M. Hedayati-Poor, J. I. Johansson, H. S. Sherif
The relativistic amplitude for the direct knock-out contribution to reactions on nuclei is reduced to a nonrelativistic form using an effective Pauli reductio…
Sensible Quantum Mechanics: Are Probabilities only in the Mind?
Don N. Page
Quantum mechanics may be formulated as {\it Sensible Quantum Mechanics} (SQM) so that it contains nothing probabilistic except conscious perceptions. Sets of these perceptions can…
Characteristics of Cosmic Time
D. S. Salopek
The nature of cosmic time is illuminated using Hamilton-Jacobi theory for general relativity. For problems of interest to cosmology, one may solve for the phase of the wavefunction…
Sensible Quantum Mechanics: Are Only Perceptions Probabilistic?
Don N. Page
Quantum mechanics may be formulated as Sensible Quantum Mechanics (SQM) so that it contains nothing probabilistic, except, in a certain frequency sense, conscious perceptions. Sets…
Time machines: the Principle of Self-Consistency as a consequence of the Principle of Minimal Action
A. Carlini, V. P. Frolov, M. B. Mensky +2
We consider the action principle to derive the classical, non-relativistic motion of a self-interacting particle in a 4-D Lorentzian spacetime containing a wormhole and which allow…
Coarse-Graining and Renormalization Group in the Einstein Universe
Alfio Bonanno
The Kadanoff-Wilson renormalization group approach for a scalar self-interacting field theor generally coupled with gravity is presented. An average potential that monitors the flu…
Orbits, forces and accretion dynamics near spinning black holes
C. Barrabes, B. Boisseau, W. Israel
We analyze the relativistic dynamical properties of Keplerian and non-Keplerian circular orbits in a general axisymmetric and stationary gravitational field, and discuss the implic…
On critical behaviour in gravitational collapse
Viqar Husain, Erik A. Martinez, Dario Nunez
We give an approach to studying the critical behaviour that has been observed in numerical studies of gravitational collapse. These studies suggest, among other things, that black…
One-loop Renormalization of Black Hole Entropy Due to Non-minimally Coupled Matter
Sergey N. Solodukhin
The quantum entanglement entropy of an eternal black hole is studied. We argue that the relevant Euclidean path integral is taken over fields defined on -fold covering of the bl…
On Some New Black String Solutions in Three Dimensions
Warren G. Anderson, Nemanja Kaloper
We derive several new solutions in three-dimensional stringy gravity. The solutions are obtained with the help of string duality transformations. They represent stationary configur…
