An intrinsic characterization of the Kerr metric

Joan Josep Ferrando, Juan Antonio Sáez

We give the necessary and sufficient (local) conditions for a metric tensor to be the Kerr solution. These conditions exclusively involve explicit concomitants of the Riemann tenso…

Re-examination of Polytropic Spheres in Palatini f(R) Gravity

Gonzalo J. Olmo

We investigate spherically symmetric, static matter configurations with polytropic equation of state for a class of f(R) models in Palatini formalism and show that the surface sing…

Improved constrained scheme for the Einstein equations: An approach to the uniqueness issue

Isabel Cordero-Carrión, Pablo Cerdá-Durán, Harald Dimmelmeier +3

Uniqueness problems in the elliptic sector of constrained formulations of Einstein equations have a dramatic effect on the physical validity of some numerical solutions, for instan…

On the algebraic types of the Bel-Robinson tensor

Joan J. Ferrando, Juan A. Sáez

The Bel-Robinson tensor is analyzed as a linear map on the space of the traceless symmetric tensors. This study leads to an algebraic classification that refines the usual Petrov-B…

The Power Spectrum in de Sitter Inflation, Revisited

Ivan Agullo, Jose Navarro-Salas, Gonzalo J. Olmo +1

We find that the amplitude of quantum fluctuations of the invariant de Sitter vacuum coincides exactly with that of the vacuum of a comoving observer for a massless scalar (inflato…

NADA: A new code for studying self-gravitating tori around black holes

Pedro J. Montero, Jose A. Font, Masaru Shibata

We present a new two-dimensional numerical code called Nada designed to solve the full Einstein equations coupled to the general relativistic hydrodynamics equations. The code is m…

Probing the creatable character of perturbed Friedmann-Robertson-Walker universes

Ramon Lapiedra, Diego Sáez

We discuss whether some perturbed Friedmann-Robertson-Walker (FRW) universes could be creatable, i. e., could have vanishing energy, linear momentum and angular momentum, as it cou…

Black hole state degeneracy in Loop Quantum Gravity

Ivan Agullo, Jacobo Diaz-Polo, Enrique Fernandez-Borja

The combinatorial problem of counting the black hole quantum states within the Isolated Horizon framework in Loop Quantum Gravity is analyzed. A qualitative understanding of the or…

Black hole state counting in Loop Quantum Gravity: A number theoretical approach

Ivan Agullo, J. Fernando Barbero G., Jacobo Diaz-Polo +2

We give a practical method to exactly compute black hole entropy in the framework of Loop Quantum Gravity. Along the way we provide a complete characterization of the relevant sect…

Mathematical Issues in a Fully-Constrained Formulation of Einstein Equations

I. Cordero-Carrión, J. M. Ibáñez, E. Gourgoulhon +2

Bonazzola, Gourgoulhon, Grandclément, and Novak [Phys. Rev. D {\bf 70}, 104007 (2004)] proposed a new formulation for 3+1 numerical relativity. Einstein equations result, according…
