摘要

The singularity theorems of Hawking and Penrose assert the presence of incomplete geodesics in the time evolution of Cauchy data with physically reasonable matter containing a trapped surface. Studying the structure of these singularities and understanding whether generically they entail a loss of predictability power of the theory have become central issues in classical General Relativity.
