What is the font used in http://www.math.harvard.edu/~kronheim/khovanov-unknot.pdf?

Answer 1

The math font is Math Time Pro 2. It's a commercial font, but you have a lite version available for free (it lacks bold versions of the characters and several companion alphabets).

If you prefer open source fonts, you can use \usepackage{txfonts} or \usepackage{mathptmx} (they are also based on Times, so will look similar, but not identical to Math Time).

Answer 2

The free tool pdffonts, part of the Xpdf package, lists these fonts:

Besides Times New Roman TrueType, there's the Monotype TimesNR Type 1 font. Have a look at Monotype TimesNR font pack on CTAN.
