Strong Cosmic Censorship for T2-Symmetric Spacetimes with Cosmological Constant and Matter
Abstract.We address the issue of strong cosmic censorship for T2-symmetric spacetimes with positive cosmological constant. In the case of collisionless matter, we complete the proof of the C2 formulation of the conjecture for this class of spacetimes. In the vacuum case, we prove that the conjecture holds for the special cases where the area element of the group orbits does not vanish on the past boundary of the maximal Cauchy development.
