%0 Journal Article %T Gravitational collapse and the formation of black holes for the spherically symmetric Einstein-Vlasov system %A Hakan Andreasson %A Markus Kunze %A Gerhard Rein %J Mathematics %D 2008 %I arXiv %X We review results on the spherically symmetric, asymptotically flat Einstein-Vlasov system. We focus on a recent result where we found explicit conditions on the initial data which guarantee the formation of a black hole in the evolution. Among these data there are data such that the corresponding solutions exist globally in Schwarzschild coordinates. We put these results into a more general context, and we include arguments which show that the spacetimes we obtain satisfy the weak cosmic censorship conjecture and contain a black hole in the sense of suitable mathematical definitions of these concepts which are available in the literature. %U http://arxiv.org/abs/0812.1645v1
