A couple of my recent questions have been on representation theory of locally compact groups and when tagging my post, I found this strange tag called representation-theorems. It's only been used by one question and I don't anticipate it being used much in the future (if at all). Should this tag be removed?
I think the tag is not informative. Knowing that something is tagged representation-theorems gives me no clue to what the question is about. Representing things by other things happens all over mathematics. I suggest retagging the question that causes the tag to exist; then the tag will be automatically removed.
