"Globally, the reviewer very much likes the spirit and the scope of the book. The writing is lively, the material is diverse and maintains a strong unity." --Zentralblatt MATH 1375
"For readers with interest in the theory or application of differential equations, integral equations, optimization, or numerical analysis, Techniques of Functional Analysis for Differential and Integral Equations is a very valuable resource. I highly recommend this book to any such person. I also believe that the book can serve as a nice supplement to more abstract texts on functional analysis, helping one to see how the abstract theory influences thinking about other areas of mathematics."--MAA Reviews
