Some examples of trapped surfaces

General Relativity and Quantum Cosmology 2011-12-23 v1

Abstract

We present some simple pen and paper examples of trapped surfaces in order to help visualising this key concept of the theory of gravitational collapse. We collect these examples from time-symmetric initial data, 2+1 dimensions, collapsing null shells, and the Vaidya solution.
