Who's afraid of a negative lapse?
Robert Beig, Piotr T. Chruściel, Wan Cong
We rederive the Arnowitt-Deser-Misner equations in a framework in which the zeros of the lapse are innocuous, whether with or without changes of sign. We further develop and analys…
Kerr-AdS type higher dimensional black holes with non-spherical cross-sections of horizons
Piotr T. Chruściel, Wan Cong, Finnian Gray
We construct, in even spacetime dimensions, a family of singularity-free Kerr-Anti-de Sitter-like black holes with negatively curved cross-sections of conformal infinity and non-sp…
Cauchy problems for Einstein equations in three-dimensional spacetimes
Piotr T. Chruściel, Wan Cong, Théophile Quéau +1
We analyze existence and properties of solutions of two-dimensional general relativistic initial data sets with a negative cosmological constant, both on spacelike and characterist…
A Bogovskiǐ-type operator for Corvino-Schoen hyperbolic gluing
Piotr T. Chruściel, Albachiara Cogo, Andrea Nützi
We construct a solution operator for the linearized constant scalar curvature equation at hyperbolic space in space dimension larger than or equal to two. The solution operator has…
