I shall discuss the Chen–Wang–Yau quasilocal angular momentum, which is defined based on the theory of optimal isometric embedding and quasilocal mass of Wang–Yau, and the limits of which at spatial and null infinity of an isolated gravitating system. This is based on joint work with Po-Ning Chen, Jordan Keller, Ye-Kai Wang, and Shing-Tung Yau.

This material is based upon work supported by the National Science Foundation under Grant Number DMS 1810856 (Mu-Tao Wang).
