Problems exporting simple LaTeX math to HTML

Problems exporting simple LaTeX math to HTML

[Richard Stanton]

[My apologies if this is a repeat. I tried posting this 4 days ago and didn’t see if appear on the list.]

I created the following very simple org file:

————


#+TITLE: *Math example*

\[ w_j = \nu_j \prod_{l<j} (1-\nu_l), \]


————

This exports to LaTeX fine, but when I export to HTML, the equation comes out as plain text

<p>
\[ w_j = \nu_j \prod_{l<j} (1-\nu_l), \]
</p>

Am I missing something?

By the way, org-version gives

Org mode version 9.0.5 (9.0.5-elpa @ /Users/stanton/.emacs.d/elpa/org-20170210/)

That's the way it should be if Mathjax is enabled (which it is by
default): Mathjax should then interpret that and print out a nicely
formatted equation when you view it in the browser. *However*, Mathjax
has a limitation with "<": one workaround is to surround the < with
spaces:

 \[ w_j = \nu_j \prod_{l < j} (1-\nu_l), \]

Seems like a bug.

To work around it, put a space between `<' and `j'.

HTH,

That works. Thanks.
