Exercises for the lecture are found here:
–Introductory reading: General relativity, Wald: chapter 11 on asymptotic flatness
References on what the course will cover:
These are lectures on the broad theme of the lectures
Lectures on charges and how they are constructed.
–Ashtekar, Asymptotic quantization 1987
Lectures on asymptotic flatness and construction of phase space
–Geroch, Asymptotic structure of spacetime, 1977
More mathematical treatment of asymptotic flatness
Papers for more advanced reading:
BMS charges and algebra are constructed
In these papers the phase space for gravitons is constructed and the BMS symmetry related to the soft graviton theorem.
Dual BMS charges are found and extended
Phase space for gravitational scattering is constructed without requiring boundary conditions at spacelike infinity leading to more general soft theorem.
