The LaTeX tool for adapting a math formula to bold text style is switching to
the math version "bold" *before* the formula.
http://ctan.math.washington.edu/tex-archive/macros/latex2e/contrib/isomath/isomath.html#math-font-selection

The switch is valid until another \mathversion command or the end of the
current group (e.g. a section command argument):

\documentclass[]{article}
\begin{document}

\section{$\mathrm{H_20}$ \mathversion{bold} $\mathrm{H_20}$}

back to normal math version $\mathrm{H_20}$
switch to bold math version \mathversion{bold} 
test $\mathrm{H_20}$

\end{document}

Some symbols don't exist in a bold version, so it may become a strange mix
of bold and normal characters, though.


There are packages that allow to define a default command for each section,
so you can automate the math version switch. If you are using the
KOMA-Script document classes, see their documentation for details.

Hope this helps,

Günter

Yes, I could edit each formula of the section title, but I would like to find
an automatic way to have these formula, let say in \boldsymbol.
Actually, my formula are already in \rm (Chemistry formula for example).
They cannot be switched in \boldsymbol, but probably in \mathbf

Hello,

I used to use small formula in section or sub-section title.
Unfortunately, if latex manage the font of the Titles (by typically
using a bold font) for the regular text, it just use the "standard"
font for the formula.
The transition from bold to regular is just ugly. Is there a way to
coordinate the fonts?

Thank.


Hi,

Just to be sure: So just using \boldsymbol manually for formulas in the 
title and headings does not work for you, right? You want it to switch 
automatically whenever the surrounding text is bold?

Can you please provide a MWE (https://wiki.lyx.org/FAQ/MinimalExample 
) to work from?
