Math 741. Topics in Partial Differential Equations: Linear Stability of Black Holes
- Spring 22 - Hans Lindblad

The lectures are MW 1.30-2.45 in Krieger 411.
The course starts with a general introduction to Einstein's equations, in particular the exact black holes solutions, and the wave equation nature of Einstein's equations, that can be found in the text books:
Carroll An introduction to general relativity: Spactime and Geometry
Hawkinng and Ellis The large scale structure of space-time
Ohanian and Ruffini Gravitation and Spacetime
Wald General Relativity
Physics Unsimplified GR Lectures
After that we will go into material from recent research papers about linear stability of black holes, by Hintz-Vasy or Fang in the case of positive cosmological constant and Holzegel-Dafermos-Rodnianski, Johnson, Hung and Haffner-Hintz-Vasy et. al. in the case of vanishing cosmological constant, to the extent that time permits. Some background in Geometry and PDE would be helpful, and for the later parts also Functional Analysis and Microlocal Analysis.
V. Schlue Linear Waves on higher dimensional Schwarzschild black holes and Schwarzschild de Sitter spacetimes
M. Dafermos, I. Rodnianski: Lectures on black holes and linear waves
M. Dafermos, I. Rodnianski: The wave equation on Schwarzschild-de Sitter spacetimes
The preliminary plan is:
Einstein's equations and the Geometry of Spacetime.
The Exact Solutions to Einstein's vacuum equations.
The Cauchy Problem in General Relativity.
The Linearized Einstein equations around the exact solutions.
The wave equation on the background of the exact solutions.
Linear stability of Black Holes with positive cosmological constant.
Linear stability of Black Holes with vanishing cosmological constant.
My Lecture notes will be available on blackboard
