Mathematics Book Recommendations

Click For Summary
The discussion revolves around recommendations for books on mathematics and functional analysis. Participants seek titles similar to two highlighted books that summarize key mathematical concepts. A notable suggestion includes a classic by Reed and Simon, which is comparable in rigor to Rudin's works. The importance of a strong foundation in real analysis before studying functional analysis is emphasized, with Rudin's "Real and Complex Analysis" recommended as preparatory reading. Kreyszig's textbook is mentioned as a more accessible option, although it does not cover some advanced topics. Additionally, Hunter's "Applied Analysis" is suggested for its practical examples. Overall, the conversation highlights the necessity of a solid background in real analysis for success in functional analysis studies.

There's this one by some Russian authors. I haven't read it.

Thank you! Good suggestion!
 
Gentlemen,
Sorry, rather than opening new thread, please let me post this question in this thread.
What book(s) would you recommend for physics student studying Functional Analysis?
Is strong background in real analysis a must prerequisite before doing Fuctional Analysis?
I observe Rudin's book is quite widely used, how about the one by Peter D. Lax?
Is it a good one? It seems it covers more topics than Rudin's does.
Any suggestion would be highly appreciated.

https://www.amazon.com/dp/0125850506/?tag=pfamazon01-20 by Reed and Simon is a well-known classic. Don't be fooled by the title, this is a real mathematics at about the same level as Rudin. It has very interesting and useful end-of-chapter notes.

A background in real analysis certainly helps.

Even though several real analysis courses were prerequisites for the functional analysis course that I took, the textbook for this course, https://www.amazon.com/dp/0471504599/?tag=pfamazon01-20 by Kreyszig, does not really require analysis. This book is a pedagogical masterpiece (read the reviews!) that is very readable; a favourite of mine. It is, however, not quite at the level of the other books mentioned, and it does not contain a treatment of distributions (e.g., Dirac delta "functions".)

I recommend going thru the first 5 chapters (at least) of Rudin's Real and Complex Analysis before tackling Rudin's Functional Analysis. I made the mistake of jumping from Royden's Real Analysis to Rudin's Functional Analysis (on self-study). Real and Complex Analysis provides some good examples and applications of some "basic" functional analysis.

I also like Hunter's Applied Analysis for motivation and examples while tackling Rudin.

Does anybody who gave advice on functional analysis books have any advice for my original question? 'Daverz' gave a really good suggestion!
