Generatingfunctionology

What Hacker News says

   Beware - one step more and you get into the region of generating functions. I recommend a book Herbert Wilf with a wonderful name of Generatingfunctionology (https://www2.math.upenn.edu/~wilf/gfology2.pdf).

   You may also like this other speech by the same author (Herb Wilf) that I love too (on an unrelated topic):

   • Epsilon Sandwiches https://www2.math.upenn.edu/~wilf/website/MAASpeech

   In fact everything by Wilf that I've read is lovely: the paper "Recounting the rationals" (https://www2.math.upenn.edu/~wilf/website/recounting.pdf with Neil Calkin), and the book generatingfunctionology https://www2.math.upenn.edu/~wilf/DownldGF.html

   Nothing to add to this except to say that Generatingfunctionology is an awesome book. Although I haven't read it, another in the same space is A=B, also co-authored by Wilf (https://www.math.upenn.edu/~wilf/AeqB.html) (another co-author is Zeilberger, whose name anyone interested in computational discrete math will recognise).

   I think the mistake in your thinking is that infinity is a value or reachable destination. It's a concept and it behaves differently than a number.

   Also go read Generatingfunctionology and Concrete Mathematics

   Great idea to compile this list. One of my favourite mathematics books that is available for free download is GeneratingFunctionology - https://www.math.upenn.edu/~wilf/DownldGF.html

   Well-written and incredibly rewarding.
