Thermodynamics of non-extremal Kaluza-Klein multi-black holes in five dimensions
Cristian Stelea, Kristin Schleich, Donald Witt
Using a solution-generating method, we derive an exact solution of the Einstein's field equations in five dimensions describing multi-black hole configurations. More specifically,…
Singularities from the Topology and Differentiable Structure of Asymptotically Flat Spacetimes
Kristin Schleich, Donald M. Witt
We prove that certain asymptotically flat initial data sets with nontrivial topology and/or differentiable structure collapse to form singularities. The class of such initial data…
Nonexistence of marginally trapped surfaces and geons in 2+1 gravity
Gregory J. Galloway, Kristen Schleich, Donald M. Witt
We use existence results for Jang's equation and marginally outer trapped surfaces (MOTSs) in 2+1 gravity to obtain nonexistence of geons in 2+1 gravity. In particular, our results…
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…
