问题
How do I get stuff like \textsc to work? Apparently it might be possible to enable it judging from this mathoverflow answer.
Has anyone else found a solution that allows using small caps or caps at least?
回答1:
APSMathJax does not include a small caps font (since this is a text font rather than a math font), so doesn't have a \textsc macro. You can simulate the effect with something like {\rm S{\small MALL}C{\small APS}}. A bit of a pain, but if you don't have a lot of it to do, it should give you a result close to what you are looking for.
