I would like to use the nice fonts (text + math) of the following document (from the Encyclopedia of Mathematical Physics).
I tried WhatTheFont but without a convenient result.

I used pdffonts command and I get a huge list of embedded fonts (strange ones as OAAALF+AdvP4E79...) and some recognizable ones (Helvetica, Sabon-Italic, CASLONOPENFACE-Thin). I ddin't get the used mathematical fonts. the nice answers given here How do I find out what fonts are used in a document/picture? do not cover math fonts!
Do you have any suggestion?
pdffonts. Right now you are just asking us to guess... – campa Aug 05 '22 at 19:54
