I would like to learn about iterative functional equations.
I read this book, but it doesn't include such functional equations. I tried this, but it was too general for my purpose. Finally I read this, witch suggests that book.
I tried to find a free copy of Smital, but I couldn't. So:
- is there a copy of that book?
- is there any book like that?
- is there any book about iterative functional equations?
Thanks in advance!
