"""The book is written in a language both accessible and attractive to students. The author succeeds in not falling into the trap of a sort of 'mathematical baby talk' to meet his goals. … Students crossing the bridge from calculus to higher mathematics will find the book very helpful. But it is also very helpful to academics in other areas who want to have access to mathematical publications relevant to their fields, but need to become familiar with the notations and language currently used by research mathematicians."" - Zentralblatt MATH, 1048"
