3-Transposition Groups


In 1970 Bernd Fischer proved his beautiful theorem classifying the almost simple groups generated by 3-transpositions, and in the process discovered three new sporadic groups, now known as the Fischer groups. Since then, the theory of 3-transposition groups has become an important part of finite simple group theory, but Fischer's work has remained unpublished. 3-Transposition Groups contains the first published proof of Fischer's Theorem, written out completely in one place. Fischer's result, while important and deep (covering a number of complex examples), can be understood by any student with some knowledge of elementary group theory and finite geometry. Part I of this book has minimal prerequisites and could be used as a text for an intermediate level graduate course; parts II and III are aimed at specialists in finite groups.


 Reviews:

"...Aschbacher's excellent book is required for all with specific interest in finite simple groups, but those with a less direct connection will also find much of value. In particular, they will filnd the only available collected treatment of Fischer's classification of 3-transposition groups, one of the most important and historic results from the theory of finite simple groups, presented lucidly by one of the most original minds in that area." Bulletin of the American Mathematical Society

' … this book offers a profound insight into the theory of finite simple groups even for non-specialists.' G. Kowol, Wien, , Monatshefte für Mathematik

'The author's main objective is to provide a proof of the theorem classifying the almost simple groups generated by 3-transpositions, which Bernd Fischer found in 1970 but never published … A specialised but important topic, which is given a very readable exposition here.' Mathematika

'I recommend the book strongly to two types of potential reader: the reader who wishes to see a proof of a beautiful and key theorem in the classification theorem explained by a master and the reader who is already expert in finite group theory and who wishes to gain detailed insight into the current programme of placing the theory of sporadic simple groups in a conceptual framework.'
