# Bold symbols for Greek letters [duplicate]

How can I get bold math symbols?

I use for bold Greek letters the command \boldsymbol for other maths expression \mathbf, but the font weight is not the same. How can I get the font weight of bold Greek letters the same as using \mathbf?

• bm package is useful for bold Greek characters. – percusse Aug 26 '12 at 10:58
• @percusse -- i'm not sure this question is the same as the one pointed out in the reason for closing. in the example there, the weight of the bold lowercase greek appears to be not as bold as that of the lowercase roman, and it isn't. default bold math (\mathbf} with computer modern fonts uses the font cmbx* which is an extended font. \boldsymbol or bm use the only cm font that is usually available in bold, cmmib10, which is not an extended font. thus the bold greek letters are indeed not as "bold" as the roman. – barbara beeton Aug 26 '12 at 18:30
