Title: DON'T buy this book!
Review: This is not the original work. Just like Emily Dickinson's poems, sometimes you get an "edited" version of a beautiful mathematical work. I am SO sorry that I bought this book. Besides the problem with messing with a finished work, there are serious errors in proofs all over the book.GetElements of the Theory of Functions and Functional Analysisinstead (also by Dover).
