LaTeX renders fine when you go to the tag-info page, for example, abelian-groups. However, when you try to add the abelian-groups tag to your post it doesn't render in the pop-up.
This is messy. Is it a known problem? Is there some sort of fix other than using words as opposed to symbols. However,
"An abelian group is a group where all the elements commute."
is woefully inadequate! Using the definition of "commute" is much better than using the word!
all the elements commute
is only 20 some odd, whereas$a*b=b*a$ for every $a,b\in G$
pushes 30. Sometimes one has to play the trade-off carefully. $\endgroup$ – Willie Wong Nov 20 '12 at 11:24
