An Introductory Course in Functional Analysis

“The text is very well written. Great care is taken to discuss interrelations of results. … Each chapter ends with well selected exercises, typically around 20 exercises per chapter. … I believe that this book is also suitable for self-study by an interested student. It can also serve as an excellent, concise reference for researchers in any area of mathematics seeking to recall/clarify fundamental concepts/results from functional analysis, in their proper context.” (Beata Randrianantoanina, zbMATH 1328.46001, 2016)

“The book is a nicely and economically designed introduction to functional analysis, with emphasis on Banach spaces, that is well-suited for a one- or two-semester course.” (M. Kunzinger, Monatshefte für Mathematik, Vol. 181, 2016)
