Groups 93 Galway/St Andrews Volume 1

This two-volume book contains selected papers from the international conference Groups 1993 Galway/St Andrews, which was held at University College Galway in August 1993. These two volumes represent the wealth and diversity of group theory. Five main lecture courses were given at the conference. These were Geometry, Steinberg representations and complexity by J. L. Alperin (Chicago), Rickard equivalences and block theory by M. Brou (ENS, Paris), Cohomological finiteness conditions by P. H. Kropholler (QMW, London), Counting finite index subgroups by A. Lubotzky (Hebrew University, Jerusalem), and Lie methods in group theory by E. I. Zel'manov (University of Wisconsin at Madison). Articles based on their lectures, in one case co-authored, form a substantial part of the Proceedings. Another main feature of the conference was a GAP workshop jointly run by J. Neubser and M. Schnert (RWTH, Aachen). Two articles by Professor Neubser, one co-authored, appear in the Proceedings. The other articles in the two volumes comprise both refereed survey and research articles contributed by other conference participants. As with the Proceedings of the earlier Groups-St Andrews conferences, the articles in these Proceedings will, with their many references, prove valuable both to experienced researchers and to postgraduates interested in group theory.
