Around 1980, G. Mason announced the classification of a certain subclass of an important class of finite simple groups known as ""quasithin groups"". The classification of the finite simple groups depends upon a proof that there are no unexpected groups in this subclass. Unfortunately Mason neither completed nor published his work. In the Main Theorem of this two-part book (Volumes 111 and 112 in the AMS series, Mathematical Surveys and Monographs) the authors provide a proof of a stronger theorem classifying a larger class of groups, which is independent of Mason's arguments. In particular, this allows the authors to close this last remaining gap in the proof of the classification of all finite simple groups. An important corollary of the Main Theorem provides a bridge to the program of Gorenstein, Lyons, and Solomon (Volume 40 in the AMS series, Mathematical Surveys and Monographs) which seeks to give a new, simplified proof of the classification of the finite simple groups. Part I (Volume 111) contains results which are used in the proof of the Main Theorem. Some of the results are known and fairly general, but their proofs are scattered throughout the literature; others are more specialized and are proved here for the first time. Part II of the work (the current volume) contains the proof of the Main Theorem, and the proof of the corollary classifying quasithin groups of even type. The book is suitable for graduate students and researchers interested in the theory of finite groups Around 1980, G.

This is the second volume of a two-volume set, which take up where Geoff Mason left off in the 1980x on the issue of quasithin groups of even characteristics. V.2 gives the proof that the groups listed in the Main Theorem are the simple quasithin groups of even characteristics--all of whose proper simple sections are known simple groups. This lively and comprehensive proof includes the structure of QTKE-groups and the main case division, treatments of the generic case and modules which are not FF-modules, and certain pairs in the FSU. While the two volumes address one issue of mathematics, they also serve as models of presentation for analyses Annotation : 2004 Book News, Inc., Portland, OR (booknews.com) Around 1980, G Mason announced the classification of a certain subclass of a class of finite simple groups known as 'quasithin groups'. The classification of the finite simple groups depends upon a proof that there are no unexpected groups in this subclass. This book offers a proof of a theorem classifying a larger class of groups. In around 1980, G. Mason announced the classification of a subclass of an important class of finite simple groups known as 'quasithin groups'. In the main theorem of this two-part work the authors provide a proof of a stronger theorem classifying a larger class of groups independently of Mason's research 1.
