I am a Ph.D. student in economics and I plan to study functional analysis by myself either this winter or the next summer. I am currently looking for a textbook, and since I am studying it by myself, I would like the textbook to have complete solutions to all or at least many (say, all odd numbered) problems. I have taken a graduate real variables sequence, but have never studied functional analysis before. So preferably, this doesn't have to be a very advanced text.
Is there any suggestions? Actually it doesn't have to be a book; well written online notes or course websites with complete solutions to exercise/homework problems would be great as well.
Of course I will attempt the problems by my own effort first, but since I won't have anyone to discuss with, I hope that I can have some last resort whenever I cannot figure out a problem.
Thank you very much!
