Jerry Griffiths is a Professor at Loughborough University, where he has worked since obtaining his PhD from the University of Wales on neutrino fields in general relativity. He continues to work on the generation and interpretation of exact solutions of Einstein's equations and has published over 80 articles on these topics. Jiri Podolsky is an Associate Professor at Charles University in Prague, where he also obtained his PhD and Habilitation in theoretical physics. His research concentrates mainly on the investigation of exact radiative and black hole space-times in general relativity. He has published over 60 papers in these fields.
This is a resource monograph well balanced between a pedagogical scientific text and a review of current research on the subject. It should be standing undoubtedly, next to the Exact solution book , on the bookshelf of both graduate students and academic researchers working on general relativity. Theophanes Grammenos, Mathematical Reviews ... tell[s] of the achievements of a generation of theorists whose only instruments were, for a good part of their lives, a pad of paper and a few pencils.
