Introduction to Lie Algebras

From the reviews:

“The book under review gives a very basic algebraic introduction to Lie algebras.

"Erdmann and Wildon’s book is more leisurely and chatty, and to my knowledge is the most readable … material that is currently in print. … In summary, I think this text may be the best pedagogical advance in the teaching of Lie algebras in the last few decades, and may in fact be the only textbook … genuinely suitable for undergraduates. … excellent book that should be carefully reviewed by anybody seeking a textbook for a course in the purelyalgebraic theory of Lie algebras." (Mark Hunacek, The Mathematical Gazette, Vol. 92 (524), 2008)

"Lie theory is a subject that is usually only taught in graduate school. … This book aims to break this barrier and gives an introduction to Lie algebras suitable for advanced undergraduate students. … contains many examples and exercises and the authors included answers to selected exercises. Overall this book is a very well thought out and well-written introduction to Lie algebras and it provides an excellent entry point into Lie theory for advanced undergraduates and early graduate students interested in learning about the subject."
