Hello everybody,
I want to know if there's any book that categorizes problems by subjects of Functional Analysis. I'm studying basic Functional Analysis now a days and I really need to solve some problems in order to assure myself that I've really understood the concepts and definitions. please tell me a book which contains lot of problems.
I like these books from Reslib library:
ResLib.com: Functional analysis
ResLib.com: Beginning functional analysis
