# May I have bold mathfraktur?

I want a bold version of $\mathfrak{H}$. How may I have one?

• unicode-math has it. For pdflatex probably not. Aug 15, 2021 at 3:52
• @Symbol1 see campa's answer... Aug 15, 2021 at 7:38
• TIL. Either I have never seen bold frak before or I did but cannot tell the difference. Aug 15, 2021 at 17:53

For reference, the unicode-math command for bold Fraktur is \symbffrak{a}.

MWE

\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage{unicode-math}
\setmathfont{XITS Math}
\begin{document}
\Large
$\symnormal{a} + \symliteral{a}+ \symbb{a} + \symbbit{a}+ \symcal{a} + \symscr{a} + \symfrak{a}+ \symsfup{a} + \symsfit{a} + \symbfsf{a} + \symbfup{a} + \symbfit{a} + \symbfcal{a}+ \symbfscr{a}+ \fbox{$\symbffrak{a}$}+ \symbfsfup{a}+ \symbfsfit{a}$

$\mathnormal{cos}\theta+ \mathbb{cos}\theta+ \mathbbit{cos}\theta+ \mathcal{cos}\theta+ \mathscr{cos}\theta+ \mathfrak{cos}\theta+ \mathsfup{cos}\theta+ \mathsfit{cos}\theta+ \mathbfsf{cos}\theta+ \mathbfup{cos}\theta+ \mathbfit{cos}\theta+ \mathbfcal{cos}\theta+ \mathbfscr{cos}\theta+ \mathbffrak{cos}\theta+ \mathbfsfup{cos}\theta+ \mathbfsfit{cos}\theta+$

$\symnormal{π} * \symliteral{π}* \symbb{π} * %\symbbit{π}* %\symcal{π} * %\symscr{π} * %\symfrak{π}* %\symsfup{π} * %\symsfit{π} * \symbfsf{π} * \symbfup{π} * \symbfit{π} * %\symbfcal{π}* %\symbfscr{π}* %\fbox{$\symbffrak{π}$}* %\symbfsfup{π}* \symbfsfit{π}$
\end{document}


You have tagged the question yourself:

\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
$\mathfrak{abc}\boldsymbol{\mathfrak{abc}}$
\end{document}


Alternatively you can use \bm from the package bm.
