DESCRIPTION:Strong cosmic censorship is the conjecture which asserts that\
 , generically\, general relativity is a deterministic theory\, in the same
  sense that classical mechanics is a deterministic theory. After an introd
 uction to the conjecture\, I will explain my recent work addressing strong
  cosmic censorship for T2-symmetric spacetimes with positive cosmological 
 constant. In the case of collisionless matter\, I will complete the proof 
 of the conjecture. In the vacuum case\, I will prove that the conjecture h
 olds for the special cases where the area of the group orbits does not van
 ish on the past boundary. Finally\, I will discuss another set of results 
 concerning the area of the group orbits for T2-symmetric solutions or hype
 rbolic symmetric solutions\, in the presence of collisionless matter.
