Formation of Trapped Surfaces in Geodesic Foliation
Formation of Trapped Surfaces in Geodesic Foliation
We revisit the classical results of the formation of trapped surfaces for the Einstein vacuum equation relying on the geodesic foliation, rather than the double null foliation used in all previous results, starting with the seminal work of Christodoulou \cite{Chr1} and continued in \cite{KRodn}, \cite{An}, \cite{AnLuk}, \cite{KLR}, \cite{An1}.
