Bold Greek with MathJax

[szho...@gmail.com]

Is it possible to use bold Greek with MathJax?  In standard LaTeX, the \mathbf command does not work on Greek letters. For example, \mathbf{\alpha} won't be upright and bold.  It does not work with MathJax either.

When using LaTeX, there are a number of packages which offer bold Greek, e.g. the bm package.  But this won't work in MathJax, of course.

So does MathJax support bold, upright Greek (something that looks comparable to \mathbf for Roman), and if yes, how can I get it to show these bold Greek symbols?

The MathJax web fonts don't include upright lower-case Greek letters (they do include upright upper-case Greek letters).  To get the upright, upper-case bold, use for example

\bf\Gamma

For upright, lower-case Greek letters, you can use the \unicode macro to obtain them from a font other than the MathJax web fonts.  For example, 

\unicode[Times]{x3BC}

would get you an upright mu from the Times font, if that is available on your reader's computer.  You could list several fonts, as in 

\unicode[STIXGeneral,Times]{x3BC}

and you can get this in bold using

{\bf\unicode[Times]{x3BC}}

There is no guarantee that your reader will have the font you specify, and the size of the character may not match the MathJax font, so this may not be optimal.

Thanks Davide,

That tells me it's probably better and more reliable to just use \vec\beta for a Greek vector than trying to get a bold β.  Reliability and clarity are more important than making the equations pretty.

Thanks!

Is there such a command for actual LaTeX or is this a mathjax special?  I do know other ways to achieve the effect using either the inputenc package or one of the new unicode-capable engines.

It is a non-standard MathJax addition.
