摘要: Our purpose is to give a taste on some global problems in General Relativity, an audience with basic knowledge intrinsic Differential Geometry. We focus the following related fundamental concept of Cauchy hypersurface: (1) smoothability and structure globally hyperbolic spacetimes, (2) initial value problem, (3) singularity theorems, (4) cosmic censorship Penrose inequality. Finally, open questions are commented.
