Groups of Exceptional Type, Coxeter Groups and Related Geometries

The book deals with fundamental structural aspects of algebraic and simple groups, Coxeter groups and the related geometries and buildings. All contributing authors are very active researchers in the topics related to the theme of the book. Some of the articles provide the latest developments in the subject; some provide an overview of the current status of some important problems in this area; some survey an area highlighting the current developments; and some provide an exposition of an area to collect problems and conjectures. It is hoped that these articles would be helpful to a beginner to start independent research on any of these topics, as well as to an expert to know some of the latest developments or to consider some problems for investigation.

Provides a quick overview of major topics in Groups and Geometries Discusses recent developments in Groups and Geometries Contains inputs from leading researchers and experts in the area Ponders on how current major issues can be settled Includes supplementary material: sn.pub/extras
