Hamiltonian formulation of general relativity and quasilocal mass

3:00pm to 4:00pm
Isometric embeddings of surfaces into the Minkowski space are used as references to derive a quasilocal mass expression from the Hamiltonian formulation of Einstein's equation. This involves an existence and uniqueness theorem of isometric embeddings and a canonical choice of time gauges. We also prove the quasilocal mass is positive under the dominant energy condition and is zero for surfaces in the Minkowski space. This talk is based on joint work with Shing-Tung Yau at Harvard.
