This book contains important review articles on topics in and closely related to the Representation Theory of Algebras. Most of them contain major new results not published elsewhere. It appears at a time of increasing interaction between the Representation Theory of Algebras and other areas of mathematics (e.g. group representations, quantum groups, vector bundles, and C* saveebras). Several of the articles are concerned with such interactions or are motivated by problems arising from them.

This book contains papers presented at the 1993 Como meeting on groups of Lie type and their geometries. Themes represented here include: subgroups of finite and algebraic groups, buildings and other geometries associated to groups of Lie type or Coxeter groups, generation, and applications. This book will be a necessary addition to the library of all researchers in group theory and related areas.
