Q: Excellent introduction to the field for physicists . Perhaps the best feature of this book is that it aims to convey the theory of Lie algebras and Lie groups to physicists. In doing so, the author is careful to give a very simplistic approach so that one not familiar with  the subject can understand it. Not to say that the book is elementary,  since it builds rapidly into the far more interesting aspects of Lie  Groups. A very good read

A: POS
****
