Not too long ago the tag context was created based on discussion in this room: chat.stackexchange.com/transcript/3740/2018/4/7

I see now that before this or similar tags has been created - but lost when the question was deleted: data.stackexchange.com/meta.math/query/858309/…

The question Putting questions on hold as off-topic was tagged missing-context, the question What further context is needed? was tagged context.

@MartinSleziak not keen on that one. automorphic-forms should suffice especially as it's easy enough to search for Maass. (Would the person's name be Mass, it might be a different situation)

I am not familiar with the area, so it is difficult for me to judge.

@barto Please could you have a look at quid's message above - concerning maass-forms.

Amusingly I just found a question about the Center of Maass.

@MartinSleziak Automorphic works for me, I don't feel strongly about the tag.
