What applies to Gödel,1 may also apply to two Schrödinger tags: schrodinger-equation and non-linear-schrodinger. The third one, schroedingers-cat, being "right" already. So, whatever you may think of the umlaut, as it is now, it is being "translated" inconsistently.
This would be a good use case for a tag synonym. Should we standardize on
o? It probably should be the former, of course, but we could run into an issue with tag length. (I think not.)
Perhaps, after a while, a mod may make a tag synonym and merge the tags into the properly spelled ones.
