Book for Hilbert spaces.

Question

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!

Answer 1

Introduction to Hilbert Spaces by Debnath is very solid and readable.

Same title by N Young is worth checking out.

Answer 2

My choice will be

Introduction to Topology and Functional Analysis by Goerge F. Simmons. You will definitely get the topics which have been mentioned here. The author provides a very simple yet elegant approach
