In this talk, I will show how basic techniques from differential geometry are applied in the research of general relativity. Specifically, I am going to examine the behavior of a model of the ``quasi-local energy'' of the gravitational field, recently proposed by Liu and Yau, near a point and near the null infinity in a 4-Lorentzian manifold. Some preliminary results of potential interest to physicists will be presented but the focus of the talk will be on the underlying geometry.
A tentative list of topics that will be discussed in the talk:
