What does Birkhoff's theorem really tell us?
Kristin Schleich, Donald M. Witt
Birkhoff's theorem is a classic result that characterizes locally spherically symmetric solutions of the Einstein equations. In this paper, we illustrate the consequences of its lo…
Charged Kaluza-Klein double-black holes in five dimensions
Cristian Stelea, Kristin Schleich, Donald Witt
Using a solution generating technique based on the symmetries of the dimensionally reduced Lagrangian we derive an exact solution of the Einstein-Maxwell-Dilaton field equations in…
Topological Obstructions To Maximal Slices
Donald M. Witt
A necessary condition for a globally hyperbolic spacetime to admit a maximal slice is that the Cauchy slice admit a metric with nonnegative scalar curvatu…
A simple proof of Birkhoff's theorem for cosmological constant
Kristin Schleich, Donald M. Witt
We provide a simple, unified proof of Birkhoff's theorem for the vacuum and cosmological constant case, emphasizing its local nature. We discuss its implications for the maximal an…
