### The Lie Algebras su(N), an Introduction

I liked your book. I did not find any errors. It was very useful for me and especially for one of my students.
B. S., Professor, NMT, USA, 4.10.2012

Your book have helped me to understand the basics of Lie Groups and Lie algebras used in particle physics. I have highly enjoyed reading this book.

I used your book on the Lie Algebras of SU(n) as a reference on that subject for a paper that I was working on at the time (which is now completed: see http://prb.aps.org/abstract/PRB/v85/i7/e075430 or http://arxiv.org/abs/1112.2709). From the point of view of a physicist, I found that the book provided a detailed, clear and easy to follow introduction to the fundamental ideas of su(n) Lie algebras and their representation theory. The inclusion of many specific worked examples was particularly useful to further my understanding of the subject.

Thank you - Yes excellent work. Wish I had these resources when I did my Masters.
I use it occasionally for teaching or when students ask me about Group Theory ( I am not a full time Tutor or a Lecturer).

I had a work to do on the SU(3) group, and your book helped me a lot. There are a lot of figures and diagrams which can help to figure out the different algebras which are not always so easy to understand.

It's a good work, well-done.
A physicist will appreciate this book because it is written from the point of view of a physicist.

...Your book did help me a lot, providing me with concise examples and detailed calculations. The numerical calculations allowed me a direct view of su(2).

…I think it is most useful as a "look up" text, almost as if it was a "solved problems" book.

... Your work is very clear and very interesting for me.
M. researcher, Ciemat, Spain, 2.4.2009

Indeed I have used this copy mostly as means of quick reference in order to make sure things I use in my work are correct. To this end it has been really useful since when studying QCD one needs to understand the structure of Lie algebras.

... I don't think that you went far enough at times.I think definitions in print of SU(5), SU(6) and SU(7)would be useful. ( A4,A5,A6 like Lie algebras). But what you did do I appreciated. You effort to make this area more understandable is commendable.
R. B., technical director, Tftn production, USA, 30.6.2007

... Your text was concise and formal, which is the best part of the text, but also makes it little boring (had it more remarks related to practical and historical things it would be much better

... My opinion on your work is quite positive! It is extremely simply written though the level is quite advanced , especially concerning the basic definitions which for most books it is an Achilles'Heel…Your language is also excellent! Not technical or trying to sound to "mathematical. For the SU(3) discussions I found it still clearer than most other textbooks! ...

D. F., Graduate Student Representative, Northeastern University, Department of Physics, 513 Dana Research Center, 1.1.2006

... The text in your work is very well written and is fun to read. Your method of constructing the SU(N) irreps is very nice and avoids the complications of the classical way. One think that is missing in your text is a more complete description of the different fundametal irreps of the SU(N) groups. In the future i'm also planning to include parts of your work while teaching the lie algebra course for physics graduates ...
