Talk:List of incomplete or incorrect mathematical proofs

"Hopelessly wrong"
Someone clean up the writing of this article. It reads like someone with no knowledge of writing factual texts wrote it.

Alright, someone is not happy with this page.

Fine, we'll improve it.

But why immediately delete it ?

Is that not a bit blatant and uncooperative ?

Lovely response to my first suggested new page.

 * Okay, I have removed the deletion notice. The original nominator may nominate it for deletion where a longer debate will occur.  I'm sorry that your first introduction to wikipedia was like this, but we do get a lot of people who don't have the best intentions for our project.  Honestly, welcome to the project!  --best, kevin [kzollman][talk] 07:07, 6 December 2007 (UTC)

Article name
If the article's new name is going to be "List of published false theorems" then it shouldn't include Kempe's (incorrect) proof of the four-color theorem, which is not a false theorem. I would prefer another name change, but I have no suggestions to make. -- Dominus (talk) 18:15, 6 February 2008 (UTC)

Gödel
The Gödel example seems to say that an offhand remark in Gödel's paper turned out to be wrong. If the remark wasn't presented as a theorem, does the example belong on the list?


 * Later mathematicians treated the claimed result as proven, so I think it does belong on the list. —Mark Dominus (talk) 07:21, 1 June 2010 (UTC)

There was a 1925 result of von Neumann and Ackermann claiming to prove that Peano arithmetic was consistent, with the proof based on a weaker metatheory. That result was of course wrong as it would contradict Gödel's incompleteness theorem. Maybe that should be added. 69.228.170.24 (talk) 06:34, 1 June 2010 (UTC)


 * Yes, definitely so. This is not the first time that has been suggested.  Please do add it.  —Mark Dominus (talk) 07:21, 1 June 2010 (UTC)

Dividing up the list
I would be in favour of dividing up: the incorrect proofs of correct theorems could usefully be separated from the claims of proofs of incorrect theorems. And incorrect proofs of results still open is another class that is worth separate listing. Perhaps some further refinements would be possible, but that would be a helpful start for the reader.

Perko pair
What's the source for the dubious claim in parentheses (at the end of the Perko pair entry)? — Preceding unsigned comment added by 69.113.194.237 (talk • contribs)

De Branges proof of the Riemann Hypothesis
I realize that listing all the incomplete and disproved attempts would be un-encyclopedic but De Branges case must be unique in that he is already credited with proving the Bierbach conjecture, a major mathematical problem, possibly even the more general Milin conjecture. His proof of the Riemann hypothesis has not been discredited, simply unverified, and what I can find online seems to suggest it is merely incomplete.

Will my fellow Wikipedians object if I add it to the list? Sources: Purdue University initial announcement https://www.purdue.edu/uns/html4ever/2004/040608.DeBranges.Riemann.html The revised paper by De Branges: https://www.math.purdue.edu/~branges/proof-riemann-2017-04.pdf An analysis by PhD Kvaalen wherein he says the proof holds if theorem 2 is correct which he cannot verify because the final statement is missing - this is what distinguishes the proof as incomplete as opposed to simply unverified, as for example Michael Atiyah's. https://eric.kvaalen.com/papers/DeBrangesMethod/index.html Calydon (talk) 23:15, 10 August 2020 (UTC)
