Title Null Geodesic Congruences, Asymptotically-Flat Spacetimes and Their Physical Interpretation
Author Timothy M. Adamo / Carlos Kozameh / Ezra T. Newman
Date accepted 5 August 2009, published 11 September 2009
FAST-TRACK REVISION  
Date accepted 23 June 2010, published 25 June 2010
Changes The two major changes are the addition of Appendix D, and that we have rewritten about a quarter of Section 7. The extra appendix was just to add new information while the changes in Section 7 were due to real errors on our part. In addition there were many very small changes, words changed here and there; a few small paragraphs were added as well. These word changes were needed to correct the errors (mainly language) in Section 7. Several misprints were also corrected and a new reference to Adamo and Newman (2010) was added.

UPDATE Publication URI: http://www.livingreviews.org/lrr-2012-1
Title Null Geodesic Congruences, Asymptotically-Flat Spacetimes and Their Physical Interpretation
Author Timothy M. Adamo / Ezra T. Newman / Carlos Kozameh
Date accepted 16 January 2012, published 23 January 2012
Changes These revisions were done exclusively by Adamo and Newman, therefore the author order was slightly changed. There was nothing essentially wrong in the earlier version, but we have included several new results (in the text and in appendices), corrected an error of interpretation in Section 7, and (the main reason for the revision) we found much easier ways of doing some of the long calculations with very much simpler arguments. 19 new references were added.
