A math book I'm studying uses a symbol and I'd like to be able to reproduce it. I used detexify to search for it, but was unsuccessful. Most likely it is the letter 'a' in some font I'm not familiar with.

Here's a zoomed in image of the symbol:

Here it is in context:

    This looks like an 'old-fashioned' German letter a, as it was used in older text books about linear algebra in Germany here

  • This sounds plausible. The book is Hoffman and Kunze's Linear Algebra, which was originally published in 1971. Jan 18 '19 at 21:45

    You find it in the MathTime Pro 2 Curly script, commercial. This picture (click) is taken from the documentation of mathalfa.

    Yes, mathtime pro 2 curly looks like it's exactly it. Thanks. Jan 18 '19 at 23:25

Since you appear to be using a bitmapped font from last century that costs money, here’s a modern equivalent. You can use whatever other TrueType or OpenType font looks better to you, but this version will automatically scale the font you select to the same height. You might want to choose it as \mathscr instead, or use \mscript for compatibility with the MathTime Pro package.

\documentclass[varwidth, preview]{standalone}

\defaultfontfeatures{ Scale = MatchUppercase }

vector space \(\mathcscr{A}\) over \(\mathcal{F}\)

Vector Space A over F

The font I used is available here.

If you want to use the original symbol, I recommend loading \usepackage[scr = mtc]{mathalfa} with an appropriate scrscaled = factor to make the font the right size.


The option of mtpccal for full mtpro2 package (not free) has the font Math Curly alphabets:
