What is your good list of more than 20 math books for functional equation with 200+ pages of each? And not very specific book with very complicated/very sophiscated topic for mathmatician please!

It is very hard to find those books at a level between advanced undergraduate to beginning graduate level these day. So i am here invite you to share some love from being share your technical experience through your past learning experience. I and the whole world wide undergraduate to graduate students would greatly appreciate your effort.

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

There is an issue in the wording of the question. Are we only supposed to post a list that contains more than 20 books? –  Matt Aug 23 '12 at 22:50
What is the significance of 20 and 200? –  user02138 Aug 23 '12 at 22:56
What makes you think there are more than 20 long books devoted to functional equations at an advanced undergraduate to beginning graduate level? Heck, what makes you think there are any? –  Gerry Myerson Aug 23 '12 at 23:25
There are more important things in maths than olympiad style functional equations. It is not a topic that one "learns", you practice and develop intuitions and techniques. –  fretty Aug 23 '12 at 23:33
Voting to close. I'm always skeptical of big-list questions, and this one is not about solving a mathematical problem, it's about stocking a library. –  Nate Eldredge Aug 24 '12 at 4:45

If you look up "functional equations" in amazon.com, you will get a number of books of varying sizes and depths.

I feel like down-voting this question for lack of effort - don't know.
