Quasi-local mass, Kerr horizon, and causality

Download to your calendar using vCal

If you have a question about this talk, please contact Justin Ripley .

I will discuss two approaches to mass in General Relativity. One quasi—local, and applicable to closed surfaces in space times (like that of the Kerr horizon), and one global, based on causal properties of space—times near space—like infinity.

The talk will take place in the Potter room, but there will also be a zoom link to join remotely:
