摘要：In general relativity, asymptotically hyperbolic manifolds serve as the initial data sets in two cases: 

(i)     asymptotically null infinity for asymptotically flat spacetimes where the cosmological constant is zero;

(ii)    asymptotically spatial infinity for asymptotically AdS spacetimes where the cosmological constant is negative.

The difference is that, in case (i), the second fundamental forms are asymptotic to hyperbolic metrics while in case (ii), the second fundamental forms are asymptotic to zero. We will discuss the positive energy theorem in the two 

cases. The talk is based on the early work of the speaker as well as the joint work with Wang Yuahua and Xie Naqing.
