missing constants on PDE

[themathsdude]

Hello,
It seems like the LaTeX environnement $$ is nested with \begin{aligh*} on _modules/stokes.md/ in a way that MathJax doesn't like here, even though it can render it on mathb.in.
The latest version of Firefox on Debian 11 renders it like this :

Also constants are missing from the original equation of the Stokes PDE on
If the PDE is in the form :
$$-\mu \Delta \mathbf{u} + \nabla p = 0$$
Then it matches the variationnal form if $\mu = \nu$ in the variationnal form, am I right ?

Here is the derivation in french : mathb.in

• OS: Debian 11
• Browser Firefox
