Complete account of a new classification of connected Lie groups in two classes, including open problems to motivate further study.

This book provides an extensive treatment of Potential Theory for sub-Laplacians on stratified Lie groups. It also provides a largely self-contained presentatio

This book is an introduction to semisimple Lie algebras. It is concise and informal, with numerous exercises and examples.

Covering subjects including manifolds, tensor fields, spinors, and differential forms, this textbook introduces geometrical topics useful in modern theoretical

"[Lectures in Lie Groups] fulfills its aim admirably and should be a useful reference for any mathematician who would like to learn the basic results for compac
