The Topology of General Cosmological Models
Gregory J. Galloway, Marcus A. Khuri, Eric Woolgar
Is the universe finite or infinite, and what shape does it have? These fundamental questions, of which relatively little is known, are typically studied within the context of the s…
Nonexistence of Degenerate Horizons in Static Vacua and Black Hole Uniqueness
Marcus Khuri, Eric Woolgar
We show that in any spacetime dimension , degenerate components of the event horizon do not exist in static vacuum configurations with positive cosmological constant. We al…
On static Poincaré-Einstein metrics
Gregory J Galloway, Eric Woolgar
The classification of solutions of the static vacuum Einstein equations, on a given closed manifold or an asymptotically flat one, is a long-standing and much-studied problem. Solu…
Bakry-Émery black holes
M Rupert, E Woolgar
Scalar-tensor gravitation theories, such as the Brans-Dicke family of theories, are commonly partly described by a modified Einstein equation in which the Ricci tensor is replaced…
Scalar-tensor gravitation and the Bakry-Emery-Ricci tensor
E Woolgar
The Bakry-Emery generalized Ricci tensor arises in scalar-tensor gravitation theories in the conformal gauge known as the Jordan frame. Recent results from the mathematics literatu…
Ricci Solitons and Einstein-Scalar Field Theory
M M Akbar, E Woolgar
B List has recently studied a geometric flow whose fixed points correspond to static Ricci flat spacetimes. It is now known that this flow is in fact Ricci flow modulo pullback by…
