This was my textbook for a graduate course in functional analysis, and it is called "classic" by many professors. Don't be fooled by the title of the book: "Introductory" simply means the author assumes you have not seen the subject before, and it is by no means an easy subject. However, the exposition is extremely clear. Kreyszig saved me on numerous occasions as my companion on a treacherous journey through graduate functional analysis.

This book does what few math textbooks do, though all of t

Kreyszig is a good writer. The book is well organized and has many examples and exercises. But it is not an advanced book in Functional Analysis.

Recommends it for: Math geeks, ML folk, and those who appreciate the aesthetic of the abstruse.
Shelves: reviewed, for-serious
This is apparently a classic text on functional analysis. While it is not perfect, I do find it to be the best thing I've read on the subject. (Thus the 5 stars -- not that it's ideal, but it's the best I've found in the area.) It's well written and more accessible than most texts at this mathematical level. (For a contrast, see my review of Grace Wahba's Spline Models for Observational Data.)

It was through this book that I first began to appreciate the awesome elegance and power of functional
