MathTime

MathTime^[1] (sometimes MathTıme) is a commercial set of Times compatible mathematical type family for TeX, created by Michael Spivak. Used together with Times or similar fonts like STIX font, it is one of the few typefaces that provide full-featured text and mathematical typesetting within TeX. MathTime has been widely adopted by academic publishers such as by Elsevier,^[2] American Physical Society,^[3] and Springer.^[4] A very distinguishable symbol in this font is the integral sign which appears in many mathematical, physical and engineering journals.^[5]

MathTime has been available in three variants:

MathTime 1.x: contains the Times compatible TeX math italic, math symbol and math extension font.
MathTime Plus: contains the Times compatible TeX math italic, math symbol and math extension font in bold and "heavy" (extra bold), used in addition to MathTime 1.x.^[6]
MathTime Professional 2: A redesigned, optical scaling (matching the 9 or 10 pt Times Ten, 7 pt Times Seven, and 5½ pt Times Small Text) version free of license restriction by Monotype Corporation, and includes (in addition to the variants from 1.x/Plus) the AMS symbols, upright script, (sans-serif) blackboard bold and "holey Roman" (serifed blackboard bold) math fonts, and extra large operators.^[7]

MathTime 1.x and MathTime Plus were sold by (the now defunct) Y&Y, while MathTime Professional 2 is marketed by PCTeX. PCTeX also offers a subset of the MathTime Professional 2 font as a "Lite" version for replacement of the basic Computer Modern fonts. For most academic writing, this Lite version is considered to be enough.

Similar typefaces[]

TrueTeX's Belleek^[8] is a metrically identical (but significantly different in shape) free replacement font for MathTime 1.x. But it has not been updated since 1997.
MicroPress' (also commercial) TM Math^[9] and the related (free) STIX fonts are similar in scope.

Also, the italicized letters v and w, when they appear in equations, but not text, have rounded (rather than pointy) bottoms, like they do in Computer Modern but not Times New Roman. These features make mathematical texts typeset using the MathTime system readily identifiable.
