I just did a little bit investigation. I find this jupyter configuration used by the jupyter web server:
..., "fullMathjaxUrl": "/static/nbclassic/components/MathJax/MathJax.js", ..., "mathjaxConfig": "TeX-AMS-MML_HTMLorMML-full,Safe", ... Hence the jupyter run by `sage -notebook` (on my system) points to "/static/nbclassic/components/MathJax/MathJax.js", and it is mathjax2. I guess you may set "fullMathjaxUrl" and "mathjaxConfig" configuration variables somehow... -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
