Title: Asymptotic charges and black hole soft hair
Abstract: I will discuss a general method of finding conserved charges in general relativity using covariant phase space methods. I will then use these results to find some charges in black hole spacetimes and derive the Hawking result for black hole entropy. I will then show how these ideas can be used in a suggestive way to find a theory that describes how black hole horizons behave.
