What program is something like this created on?

Been trying to further improve my LaTeX skills, and such to make my notes look better. But I was curious if you guys could easily tell what program something like this was created in?

Use the amsart or article class. –  Sigur May 3 '14 at 15:57
The PDF document properties show that it was created as a DVI, which implies a LaTeX > DVIPS > PS2PDF workflow. Also, the fonts include Computer Modern. The formatting of \section as centred small caps point to amsart. –  Werner May 3 '14 at 16:05
@Werner oops sorry I was just getting those but I see you'd commented before my answer:-) –  David Carlisle May 3 '14 at 16:10

@Werner -- although amsart is a good suspect, it's not using the default dimensions; the default width is 30pc and this measures 39pc, so some adjustments have been made, either directly or through use of a package. –  barbara beeton May 3 '14 at 21:43

Run it with pdflatex, xelatex, lualatex, ... (whatever you may prefer)

\documentclass{amsart}
\usepackage[math]{blindtext}
\begin{document}

\section{foo bar and baz :-)}
\blindmathpaper

\end{document}

The postscript was made with dvips(k) 5.96.1 and converted to pdf with GPL Ghostscript 8.70 It is set using Computer Modern Roman font.

(Just looking at the PDF properties in the file)
