Summary: read a Lie groups math book FIRST
Comment: Book: Quantum Mechanics - Symmetries, 2nd edition, 15 chapters, 496 pages
Scope of the book: applications of group theory in elementary particle physic (no field theory!)
Reader: PhD student in physics, I am a beginner in that area, this is my first book in symmetries and Lie groups.
My evaluation:
The math sections in the book give u some basic notion of Lie groups but are NOT sufficient to fully understand the logic behind the scene everywhere. My advice is to read some good book in Lie groups in advance.
The strongest feature of the book is its richnes of examples and solved exercises both in group theory and in its application to particle physics. You can learn a lot of analytical 'tricks' from the solutions.
At the same time the text is full of small errors (signs, indexes, equation numbers, misprints). They are easy to detect and fun to debug and keep you concentrated while debugging.
My main objection is that very often the logic in the text remains hidden, broken or fuzzy. Sometimes they prove some statement but at the end you can't tell what was actually proven or under what conditions that proof is valid, what facts it is derived from, does it rely on implicit assumptions or it's generaly true. As a consequence of that you are not sure if you can apply the statement for a situation that is not exactly the one discussed in the book. Sometimes it's hard to tell if they are talking about a necessary of sufficient condition or both. Or they, having something in mind that you don't know about, make some sudden assumption and you wonder why (example: equation (13.3) on page 442 assumes that the parity transformed wave function is proportional to the old one. why? cause they assume implicitly without stating it that parity commutes with the Hamiltonian, hence they have common eigenfunctions). Some concepts are not defined sharply from the begining but instead the authors use fussy definitions and define them much later (example: tensor product of multiplets and its reduction is defined understandably in chapter 10 but is used all the time before that). The explanations of the algebra in the examples and exercises is also not the best since in many cases I see a more logical, organized and understandable way to explain it to the reader. Also in some cases the book gives just the algebra without giving the reader the more fundamental cause for some fact(example: in exercise 8.3 page 255 they have two matrices connected by a similarity transformation, they prove with some algebra that the eigenvalues remain the same but don't tell you that's always the case with similarity transformations).
To my opinion the authors have to a lot of work to do to make the logic structure of the text (the connections between different statements,the difference between assumptions and derivable facts) fully explicit and understandable to the reader everywhere in the text. Without that, the book can be regarded as a nice collection of solved examples and exercises in group theory and particle physics.
I give that book 3 out of 5 stars and hope that the other volumes of the sequence don't have that flaw.

Summary: One of the best Textbooks on non relativistic QM
Comment: I've read all the 3 Greiner's books concerning non relativistic Quantum Mechanics (and other on QFT). First I've to underline that you may find many text-errors in those books. (QM: an introduction, QM:Special Chapters, QM:Symmetries): for everybody who is a bit familiar with Mathematics this can not be a big problem. On the second hand, you have to read all the 3 Greiner's books on Q.M. to have a great overview on this matter: every mathematical part is essential but complete. One has to follow and understand most of the calculations inside: this is the only way, generally in Physics, to earn a good Mathematical level, and be able not to concentrate too much on Mathematics while trying to understand the Physics behind. As last point I've to underline that only by reading Greiner's "Relativistic Quantum Mechanics" book, one is able to understand the meaning of introducing Field Theory formalism in "Q.M.:Special Chapters" and will appreciate it a lot: in fact everything is going to be easier on the following matters; apart of this I think it's great to treat Statistical Mechanics with operators as soon as possible, as Greiner does in Q.M.:special chapters. Lot's of importance is given to symmetries and Group theory (Q.M:symmetries) as a modern point of view pretends.

Summary: quantum mechanics symmetries
Comment: This is the most stupid book that I have ever seen. The main concepts of Elementary Particles Theory are introduced before the Quantum Field Theory has been developed. Without knowing Dirac's equation how on the Earth is possible to grasp the intricasies of Modern Physics? Lee groups are not introduces properly either -- the level of mathematical discussion is very low. For all of you who wants to use comprehensive series on Modern Physics I recommend the old ones by Landau and Lifshitz.
