I was given -100 reputation for this sound mathematical post https://mathoverflow.net/questions/473947?noredirect=1#comment1231454_473947
This is excessive and I want to dispute this decision, how do I do this?
I propose to compromise and edit the question so that it only concerns results by deceased or retired authors. Here is what I propose:
What are some theorems by deceased or retired authors published in peer reviewed journals or otherwise reputable sources that are widely accepted to be true but that you happen to know are actually false?
I am guessing we all encounter this from time to time, but there is no appropriate place to share them. Slowly but surely the mathematical literature is becoming a minefield if we all keep this information to ourselves. I will start with sharing an example. It concerns homotopy invariance of the Leray-Schauder fixed point index for compact and compactly fixed maps which I explained in detail here.
Thanks a lot for sharing your knowledge!
Note: the above question is different from this question which concerns results that are currently widely accepted to be false.
Thanks
Here's a screenshot of the question, containing all the body text. The title of the question is the same as the first sentence.
