Abstract Root Subgroups and Simple Groups of Lie Type

"This book is of interest to mathematicians working in different areas such as finite group theory, classical groups, algebraic and Lie-type groups, buildings and generalized polygons. It will also be welcomed by the graduate student in any of the above subjects, as well as the researcher working in any of these areas. Parts of it can also be used for graduate classes. Large parts of the book are self-contained and accessible with reasonable knowledge in abstract groups theory and classical groups.

Its main purpose is to give complete and partially new proofs of results that are quite unaccessible in the literature."--BOOK JACKET.
