TITLE: Book for Hilbert spaces.
QUESTION [9 upvotes]: Which book either on functional analysis or specifically for Hilbert spaces has the best way of explaining with most examples and to the point without much applications. I studied Limaye's book and Kreyszig's book but all the books on functional analysis are too clumsy for me. I want to mainly study eigenspectrums, and compact operators and Hilbert spaces for an exam. So any book, that will help me through it. Thanks!

REPLY [5 votes]: Introduction to Hilbert Spaces by Debnath is very solid and readable. 
Same title by N Young is worth checking out.
