Explore a comprehensive lecture on static black hole uniqueness theorems delivered by Carla Cederbaum from the University of Tubingen, Germany. Delve into the intricacies of classical extension, spacetime, and cross-sections as part of the ICTP School on Geometry and Gravity. Examine the concept of black hole uniqueness and its implications. Investigate the translation of these theories to scenarios involving a single black hole. Analyze the boundary conditions of all manifolds and learn how to foliate within the manifold. Conclude with a detailed proof of the static black hole uniqueness theorem, gaining a deeper understanding of this fundamental concept in theoretical physics and mathematics.
