"The book presents in a balanced way both theory and applications of interest rate modeling. …The book can serve as a textbook. It is self-contained in mathematics and presents rigorous justifications for almost all results. Many exercises are provided which often require computer implementation. To a large extent, this book can also serve as a research monograph as it contains many new results. The book shows the readers what has to be a competent quantitative analysis in financial markets." -Pavel Stoynov, Zentralblatt MATH1173.
