# The Classification of Finite Simple Groups: Groups of Characteristic 2 Type

Share this page
*Michael Aschbacher; Richard Lyons; Stephen D. Smith; Ronald Solomon*

The book provides an outline and modern
overview of the classification of the finite simple groups. It
primarily covers the “even case”, where the main groups
arising are Lie-type (matrix) groups over a field of characteristic
2. The book thus completes a project begun by Daniel Gorenstein's 1983
book, which outlined the classification of groups of
“noncharacteristic 2 type”.

However, this book provides much more. Chapter 0 is a modern
overview of the logical structure of the entire
classification. Chapter 1 is a concise but complete outline of the
“odd case” with updated references, while Chapter 2 sets
the stage for the remainder of the book with a similar outline of the
“even case”. The remaining six chapters describe in detail
the fundamental results whose union completes the proof of the
classification theorem. Several important subsidiary results are also
discussed. In addition, there is a comprehensive listing of the large
number of papers referenced from the literature. Appendices provide a
brief but valuable modern introduction to many key ideas and
techniques of the proof. Some improved arguments are developed, along
with indications of new approaches to the entire
classification—such as the second and third generation
projects—although there is no attempt to cover them
comprehensively.

The work should appeal to a broad range of
mathematicians—from those who just want an overview of the main
ideas of the classification, to those who want a reader's guide to
help navigate some of the major papers, and to those who may wish to
improve the existing proofs.
