What font is it that was used in this document?

I was wondering if anyone knows the name of the font used in screenshot below? Thanks in advance!

• if you have the pdf you don't need to guess, pdffonts utility or fonts menu of your pdf viewer will list the fonts, see above link Commented Oct 2, 2023 at 17:33

This seems to be Palatino, with math from mathpazo. Just to point out: you can also use this font with the more recent (and actively maintained) bundle newpx, although the math font is slightly different (the greek letters differ a bit, for example).

\documentclass{article}
\usepackage{amsmath}
\usepackage{mathpazo}
\begin{document}
\setcounter{section}{3}
\setcounter{subsection}{2}
\subsection{The proof of the if''-part of Theorem 3.1}
Suppose that $$f$$ satisfies multiplicative symmetries. Denote by $$\sigma(N)$$ the sum of the positive divisors of $$N$$. By Lemma 3.3, we have
\begin{align*}
& \epsilon_N q^{\sigma(N)} \prod_{\substack{ad=N \\ 0\leq b<d}} \Bigl( f^{(as)} (\zeta_d^b q^{a/d}) - f^{(as)}(r) \Bigr) \\
& = \prod_{\substack{ad=N \\ 0\leq b<d}} \biggl( 1 - \zeta_d^b q^{a/d} f^{(as)}(r) + \sum_{m=2}^\infty H_{m-1}^{(as)} \zeta_d^{bm} q^{am/d} \biggr)
\end{align*}
\end{document}


It's called Palatino.

I highly recommend to look at: How do I find out what fonts are used in a document/picture? which was suggested in this comment by David Carlisle, but the top answer to that question requires you to have a PDF file with the font in it.

Fortunately, even without the PDF file I was able to recognize this font because I have used it for almost all of my papers, for example here, and here and here.

• I did not look at all links, but in your first manuscript you seem to mix palatine text with computer modern math. Commented Oct 2, 2023 at 18:00
• Thanks for pointing that out! I did use palatino in all of those papers, but it's true that for the first paper I also used computer modern for the math-mode parts (still the vast majority of the paper uses palatino). mickep and I had a discussion about this here in case anyone is interested.
