By default, the inline and block equations are exported to Markdown in a format that can be rendered using MathJax. You can find one MathJax config example below.
oxhugo
indirectly extends from oxhtml
and so it also inherits a
different way of exporting L^{a}T_{e}X equations — by exporting them
to images.
Inline equations #
 Inline equations are wrapped between
\(
and\)
.
$
wrapping also works, but it is not preferred as it comes with restrictions like “there should be no whitespace between the equation and the$
delimiters”.So
$ a=b $
will not work (it will look like: $ a=b $), but$a=b$
will work (it will look like: \(a=b\)).On the other hand, both
\(a=b\)
(it will look like: \(a=b\)) and\( a=b \)
(it will look like: \( a=b \)) will work.

 Oneperline equations are wrapped between
\[
and\]
or$$
delimiters.
For example, below in Org:
LaTeX formatted equation: \( E = J \sum_{i=1}^N s_i s_{i+1} \)
will look like this in Hugo rendered HTML (using MathJax):
LaTeX formatted equation: \( E = J \sum_{i=1}^N s_i s_{i+1 }\)
Here’s another example, taken from Org Info: LaTeX fragments:
If $a^2=b$ and \( b=2 \), then the solution must be either
$$ a=+\sqrt{2} $$ or \[ a=\sqrt{2} \]
Above renders to below using Mathjax:
If \(a^2=b\) and \( b=2 \), then the solution must be either \[ a=+\sqrt{2} \] or \[ a=\sqrt{2} \]
Note that the last two equations show up on their own lines because
those equations are wrapped in \[ .. \]
.
L^{a}T_{e}X Environments #
oxhugo
support L^{a}T_{e}X environments.
So below in Org buffer:
\begin{equation}
\label{eq:1}
C = W\log_{2} (1+\mathrm{SNR})
\end{equation}
will render as below using MathJax:
\begin{equation} \label{eq:1} C = W\log_{2} (1+\mathrm{SNR}) \end{equation}
You can find many more equation examples at tests tagged equations.
Referencing Equations #
Equation referencing will also work but it requires MathJax. Here
is a MathJax configuration that is known to work for this referencing
feature. \label{SOMELABEL}
labeled equations can be referenced using
\ref{SOMELABEL}
^{1}. So \ref{eq:1}
will render as \ref{eq:1}
and link to the equation above.
MathJax config example #
Here’s how MathJax is configured for this website:

Exporting L^{a}T_{e}X equations as images #
If you prefer, you can using dvisvgm
or dvipng
^{2} to export the
equations to SVG or PNG images, and the equations in the Org file will
be replaced by links to those images in the exported Markdown files.
The method for exporting the equations to images is the same as that
documented for oxhtml
in Org Info: Math formatting in HTML export:
 To export the equations to SVG, add
#+options: tex:dvisvgm
to the top of your Org file, or add:EXPORT_OPTIONS: tex:dvisvgm
to the post subtree’s property drawer.  Similarly, to export the equations to PNG, use the
tex:dvipng
option instead.
Referencing to equations using \ref{..}
will not work if equations
are exported as images.
