<p>“This book is an interesting compilation of mathematical concepts and structures. … chapters are stand-alone, allowing readers to pick and choose the subjects they want to explore further. … useful as a supplement to a textbook in a traditional course or for students seeking to learn a little about a particular topic. … for the interested student at the graduate or a very advanced senior undergraduate level, it is a well-written book on independent topics. Summing Up: Recommended. Graduate students.” (S. L. Sullivan, Choice, Vol. 53 (8), April, 2016)</p><p>“This book would be an excellent reference for graduate students in just about any area of pure or applied mathematics … . It should also be accessible to researchers in (for instance) chemistry, physics, computer science, and mathematical biology. University libraries should certainly addit to their collections, and many may find a personal copy worth while.” (Robert Dawson, zbMATH 1329.00002, 2016)</p>
