My PhD advisor, Robin Pemantle, has published a book. It’s Analytic Combinatorics in Several Variables, co-authored with Mark Wilson.
As of right now customers who have viewed this item have also viewed, according to Amazon:
- Analytic Combinatorics, by Philippe Flajolet. As Flajolet’s book is to univariate analytic combinatorics what Pemantle-Wilson promises to be to multivariate analytic combinatorics, no surprise there.
- Inferno by Dan Brown. Not the computer scientist dan brown, the author.
I can infer from this:
- the probable existence of an (aspiring?) analytic combinatorialist out there who reads Dan Brown.
- that Amazon’s “customers who have viewed this item have also viewed” is pretty close to being what it says it is. In particular, there isn’t some prior in there that assumes that people who buy Pemantle-Wilson are likely to buy other math books and steers them in that direction.

It is about precisely what information you can extract from things like “You might also like” or “also viewed”.
I am not that combinatorialist. (Well, I’m really not an analytic combinatorialist.)
Sure, but you’re more relevant than Dan Brown the author.
Oh, hi dan [from down the hall]!
