Title: Some Geometrical Problems in General Relativity

Abstract: There has been a natural connection between geometry and gravity 
since Einstein. In this talk, we will discuss some geometrical problems relating to 
the positivity of the total energy-momentum in general relativity . The unsolved 
problems on the collision and the nonlinear stability of black holes will also be 
discussed.
