Hypersurface data: General properties and Birkhoff theorem in spherical symmetry
Marc Mars
The notions of (metric) hypersurface data were introduced in [Mars,2013] as a tool to analyze, from an abstract viewpoint, hypersurfaces of arbitrary signature in pseudo-riemannian…
New characterization of Robertson-Walker geometries involving a single timelike curve
Marc Mars, Raül Vera
Our aim in this paper is two-fold. We establish a novel geometric characterization of the Roberson-Walker (RW) spacetime and, along the process, we find a canonical form of the RW…
Covariant definition of Double Null Data and geometric uniqueness of the characteristic initial value problem
Marc Mars, Gabriel Sánchez-Pérez
The characteristic Cauchy problem of the Einstein field equations has been recently addressed from a completely abstract viewpoint by means of hypersurface data and, in particular,…
Analyticity of stationary spacetimes from maximal hypersurfaces
Piotr T. Chruściel, Marc Mars
The standard method of proving analyticity of stationary vacuum metrics invokes the quotient-space version of Einstein equations. We verify that the same conclusion can be obtained…
Covariant classification of conformal Killing vectors of locally conformally flat -manifolds with an application to Kerr-de Sitter
Marc Mars, Carlos Peón-Nieto
We obtain a coordinate independent algorithm to determine the class of conformal Killing vectors of a locally conformally flat -metric of signature modulo conformal…
General matching across Killing horizons of zero order
Miguel Manzano, Marc Mars
Null shells are a useful geometric construction to study the propagation of infinitesimally thin concentrations of massless particles or impulsive waves. After recalling the necess…
