Exercises in Functional Analysis (Texts in the Mathematical Sciences (closed))
From the reviews:"The present book is one of the few books available with problems in functional analysis. … the authors have done a good job in crediting the original sources of the problems. … The layout and the exposition of the book is very good. The book will be of great help to graduate students in mathematics … . will also be very helpful to research mathematicians in analysis … . I strongly recommend the book to any person who is interested in analysis and its applications." (C. D. Aliprantis, Mathematical Reviews, Issue 2005 b)
