Title: Quasilocal mass for general domains in space
Abstract: Diffeomorphism-invariant quasilocal mass in classical general relativity has been studied for decades, but it is still an open problem how to define quasi-local mass for general domains with multiple boundaries in space. Using the Hamiltonian formulation, we will provide a new way to define the nonnegative quasi-local mass, and give recent progress in overcoming the difficulties.
