 Geometry Search for the term Geometry in any field. Queries are case-independent. Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact. "Topological group" Phrases (multi-words) should be set in "straight quotation marks". au: Bourbaki & ti: Algebra Search for author and title. The and-operator & is default and can be omitted. Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff. "Quasi* map*" py: 1989 The resulting documents have publication year 1989. so: Eur* J* Mat* Soc* cc: 14 Search for publications in a particular source with a Mathematics Subject Classification code (cc) in 14. "Partial diff* eq*" ! elliptic The not-operator ! eliminates all results containing the word elliptic. dt: b & au: Hilbert The document type is set to books; alternatively: j for journal articles, a for book articles. py: 2000-2015 cc: (94A | 11T) Number ranges are accepted. Terms can be grouped within (parentheses). la: chinese Find documents in a given language. ISO 639-1 language codes can also be used.

Finite group theory. 2nd ed. (English) Zbl 0997.20001
Cambridge Studies in Advanced Mathematics. 10. Cambridge: Cambridge University Press. xi, 304 p. £ 52.50; $74.95 hbk; £ 19.95,$ 32.95 pbk (2000).
In this second edition of Aschbacher’s monograph on finite groups a number of misprints of the first edition (1986; Zbl 0583.20001) have been removed. However, this new edition has two major improvements: Chapter 15 has been completely rewritten. It contains now a proof of the solvable 2-Signalizer Functor Theorem instead of the solvable Signalizer Functor Theorem of the first edition. In confining to the more special form of this theorem the proof has become considerably more transparent. The second major change is the addition of an appendix. In this extensive appendix carefully worked out solutions of selected exercises are presented. This should even more challenge the ambitious reader to tackle the demanding exercises of this book. In conclusion: this monograph has received some valuable improvements. This confirms the opinion of my first review: I consider this book as an extremely valuable source and help for anyone interested in a serious study of finite groups.
