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

Lie groups and Lie algebras have become essential to many parts of mathematics and theoretical physics, with Lie algebras a central object of interest in their

This textbook treats Lie groups, Lie algebras and their representations in an elementary but fully rigorous fashion requiring minimal prerequisites. In particul

This book provides an introduction to Lie groups, Lie algebras, and repre sentation theory, aimed at graduate students in mathematics and physics. Although ther

It is remarkable that so much about Lie groups could be packed into this small book. But after reading it, students will be well-prepared to continue with more
