Differential Invariants of the Kerr Vacuum
Kayll Lake
The norms associated with the gradients of the two non-differential invariants of the Kerr vacuum are examined. Whereas both locally single out the horizons, their global behavior…
Cauchy horizons in Gowdy space times
Piotr T. Chruściel, Kayll Lake
We analyse exhaustively the structure of \emph{non-degenerate} Cauchy horizons in Gowdy space-times, and we establish existence of a large class of non-polarized Gowdy space-times…
An explicit global covering of the Schwarzschild-Tangherlini black holes
Kayll Lake
Explicit regular coordinates that cover all of the Tangherlini solutions (Schwarzschild black holes of dimension ) are given. The coordinates reduce to Israel coordinates for…
Galactic Potentials
Kayll Lake
The information contained in galactic rotation curves is examined under a minimal set of assumptions. If emission occurs from stable circular geodesic orbits of a static sphericall…
