SUMMARY:Monotonicity of quasilocal mass for asymptotically flat Riemannian manifolds
DESCRIPTION:Member Seminar \nSpeaker: Jue Liu \nTitle: Monotonicity of quasilocal mass for asymptotically flat Riemannian manifolds \nAbstract: The study of quasilocal mass in general relativity has a long history. In previous papers by many authors we have a deep understanding of the properties of quasilocal mass such as positivity\, rigidity and asymptotics etc. In this talk I will focus on the monotonicity of quasilocal mass\, which means the quasilocal mass of a finite region is smaller than that of a larger region containing the previous region. Motivated by the definition of Bartnik mass and Brown-York mass\, we define a new quasilocal mass using the Hamilton method. With this definition\, we derive the sufficient condition such that the quasilocal mass is monotonic. As an application I will also discuss the relationship with the Bartnik conjecture\, that is under what conditions there will be a static extension to the given Bartnik data.
