The current answers to the Academia HNQ Should I ask for permission to name a mathematical theorem? include the following (small excerpts):
There is no need to ask permission, and mostly likely they will be happy to have the theorem referred to with their names.
I suppose there is no formal need to ask for permission, but
- I see no harm in doing so.
- I see the potential for harm in not doing so.
The first can be loosely paraphrased as "go for it" and "it would be bad if you didn't" but the second seems like excellent advice.
I thought I'd ask here if there are any examples that might inspire words of caution as expressed in the 2nd answer, so I'd like to ask:
Question: Has there ever been a case where someone wished a theorem or important result wasn't named after them? Has it happened more than once?
