"This book is really quite unusual among works in analytic number theory since it provides a rather quick line of ascent to something not only pretty exotic and exciting but also absent from the usual repertoire of a practitioner of the art... Topics in Number Theory is a very interesting book indeed." Read the full review here.

"The book is very well written, the arguments are complete and many illustrative examples are given. It can be helpful to all: beginners as well as advanced researchers who want to deepen their knowledge and develop correct intuition about the topic discussed."

"A noteworthy feature of the book is that eleven of the chapter authors work in mainland China ... The edited collection is a significant contribution to the research literature and provides an important resource in the field."

"I recommend this book for everybody starting to apply, learn or teach Lie theory, and also for researchers whose work is related to Lie theory. Anybody who has anything to do with Lie theory should place this book on his/her bookshelf."

"This book contains a lot of material that can be useful for researchers in the field of critical point theory and its applications."

"This book may be useful and inspiring for a quite broad audience. Reading the text needs motivation, experience and endurance, but it is worth one¡¯s while."
