If something is possible it would be a hack of the Math JavaScript library you are using (MathJax is the default in Quarto and it works on "body"). Note that you should not have such metadata as those informations are read by many tools (including browser). |

If this is what happens, this is not because Math is not working. This is because you are tryting to write Markdown syntax (for Pandoc to interpret) using YAML configuration. So you need to handle YAML syntax and Markdown Syntax compatibility, which is escaping.
In YAML, "" or '' does not mean the same thing, and it does not escape the same.
* https://yaml.org/spec/1.2.2/#731-double-quoted-style
This is the only style<https://yaml.org/spec/1.2.2/#node-styles> capable of expressing arbitrary strings, by using “\” escape sequences<https://yaml.org/spec/1.2.2/#escaped-characters>. This comes at the cost of having to escape the “\” and “"” characters.
* https://yaml.org/spec/1.2.2/#732-single-quoted-style
The single-quoted style is specified by surrounding “'” indicators. Therefore, within a single-quoted scalar, such characters need to be repeated. This is the only form of escaping performed in single-quoted scalars. In particular, the “\” and “"” characters may be freely used. This restricts single-quoted scalars to printable<https://yaml.org/spec/1.2.2/#character-set> characters. In addition, it is only possible to break a long single-quoted line where a space<https://yaml.org/spec/1.2.2/#white-space-characters> character is surrounded by non-spaces<https://yaml.org/spec/1.2.2/#white-space-characters>.
So you can do
title: 'This is Math: $\pi$'
or
title: "This is Math: $\\pi$"
Visually in your HTML output you'll get math rendered in your Title.
However, as mentioned already in previous answer, it can have undesired side effect. Let me give details.
title can be used also in metadata of the document usually in <head> and for example you'll end up with
<title>This is Math: \pi</title>
which also will show in your browser tab as name
image.png (view on web)<https://github.com/user-attachments/assets/e0f7e6ce-304c-49a1-846e-3ab8012a88c6>
where \pi can't be rendered like in document
image.png (view on web)<https://github.com/user-attachments/assets/780131de-a30c-4b4b-8e00-9b439c7479fa>
For this specific case you could adapt using
…---
title: 'This is Math: $\pi$'
pagetitle: This is Math !
format: html
---
Content
Anyhow, you know how to do this now. Hope it helps!

Is there any way to include math formulas (TeX) in the title (metadata) for html and revealjs format?
