The Λ to zero limit of spacetimes and its physical interpretation

by Mark Bugden, Claudio Paganini




Classical and Quantum Gravity, Volume 36, Issue 4, article id. 045003.


We study the Λ→0 behaviour of Schwarzschild-de Sitter spacetime and show, according to Geroch's notion of spacetime limits, that it converges to the Schwarzschild spacetime. We use an embedding into AdS3 to illustrate and quantify this limiting behaviour.

About the Co-Author

Mark has a background in mathematics and physics, completing his PhD in String Theory and higher-dimensional black holes (Australian National University, Canberra). During postdocs in the Czech Republic (Charles University, Prague) and Germany (Max Planck Institute, Konstanz), he developed an interest in, and experience with, neural networks and machine learning. At dida he works as a Machine Learning Scientist, bridging the gap between theoretical and practical.
