Global characteristic problem for the Einstein vacuum equations with small initial data, (II): The existence proof

Abstract

This is the second part of our result on a class of global characteristic problems for the Einstein vacuum equations with small initial data. In the previous work denoted by (I), our attention was focused on prescribing the initial data satisfying the costraints imposed by the characteristic problem. Here we show how the global existence result can be achieved. This part is heavily based on the global results of D.Christodoulou, S.Klainerman and S.Klainerman, F.Nicolo`.
