We show that the Proca equation in vacuum, as well as its plausible modifications in dielectric media, is incompatible with experimental evidence, no matter how small the Proca mass is.

Asymptotic flatness in higher dimensions

Autor: Piotr Tadeusz Chruściel, Peter Cameron

We show that ( n + 1)-dimensional Myers–Perry metrics, n ≥ 4, have a conformal completion at space-like infinity of C n−3,1 differentiability class and that the result is optimal in even spacetime dimensions. The associated asymptotic symmetrie

Construction of N-body time-symmetric initial data sets in general relativity

Autor: Piotr Tadeusz Chruściel, Justin Corvino, James Isenberg

Publikováno v: University of Vienna-u:cris

Given a collection of N asymptotically Euclidean ends with zero scalar curvature, we construct a Riemannian manifold with zero scalar curvature and one asymptotically Euclidean end, whose boundary has a neighborhood isometric to the disjoint union of

On space-times with U(1) × U(1) symmetric compact Cauchy surfaces

Autor: Piotr Tadeusz Chruściel

Publikováno v: Scopus-Elsevier

General space-times evolving from U (1) × U (1) symmetric Cauchy data prescribed on compact Cauchy surfaces are studied. Existence and properties of solutions of the constraint equations are analyzed. Some “canonical” forms of the metric are der

On analyticity of static vacuum metrics at non-degenerate horizons

Autor: Piotr Tadeusz Chruściel

Publikováno v: Scopus-Elsevier
ResearcherID

We show that static metrics solving vacuum Einstein equations (possibly with a cosmological constant) are one-sided analytic at non-degenerate Killing horizons. We further prove analyticity in a two-sided neighborhood of "bifurcate horizons". It is a
