CalTitle1: Schlue -- Geometry of expanding black hole cosmologies
Geometry and Topology Seminar
Geometry of expanding black hole cosmologies
Volker Schlue (Melbourne)
Please join us for lunch before the talk. We are meeting at 12:30 on Carslaw level 2.
In general relativity, the so called Schwarzschild de Sitter spacetimes are the simplest models of a black hole in an expanding universe. I will describe the geometry of these 3+1-dimensional Lorentzian manifolds, and describe progress on a related stability problem for the Einstein vacuum equations. It turns out that the conformal Weyl curvature plays a central role in understanding the evolution of expanding spacetimes, and I will discuss a phenomenon known as the global redshift effect.
