This probably feels like a nitpick, but there are explicit cases where bounds can be astronomically high (for example, we only know for certain that [[Chen's theorem#Variations]] holds above <math>e^{e^{36}} \approx 1.7\cdot10^{1872344071119343}</math>) and until we have a bound, we can't say that the conjecture is true in full generality. To justify this, another conjecture known to hold for sufficiently large values but that is still listed as unsolved is [[Sendov's conjecture]]; [[Terence Tao]] proved the sufficiently-large part in 2020.

The brief description says: "Dubner's conjecture: every number greater than {\displaystyle 2408}{\displaystyle 2408} is the sum of two primes which both have twins." But the linked article describes the conjecture as: "every even number greater than 4208 is the sum of two t-primes". It's trivially apparent that the word "even" is required. And there is an inconsistency about the threshold number - which is it? [[User:RMGunton|RMGunton]] ([[User talk:RMGunton|talk]]) 09:42, 18 November 2022 (UTC) |

Suggestion for improvement
This is an excellent collection of unsolved problems in mathematics, unparalleled by any other list I know of.
But many, many of the problems are listed solely by name without any explanation of what the problem is.
These problems are in almost all cases linked to a description of the problem named.
But that does not work for a long list: A reader cannot be constantly clicking on links and then the back button.
Much more useful are the problem for which at least a rough description is included in the article.
SO: This article will become more and more useful as more and more problem descriptions are added. 2601:200:C000:1A0:144F:3970:779E:D68C (talk) 01:42, 27 April 2022 (UTC)
- Good point. I'll be adding short descriptions to the best of my ability soon. GalacticShoe (talk) 02:48, 27 April 2022 (UTC)
- It took a long time, but short descriptions have finally been added to most of the listed problems. GalacticShoe (talk) 01:47, 26 June 2022 (UTC)
The Erdős–Faber–Lovász conjecture has been proved
According to the Wikipedia article of the same name, "A proof of the conjecture for all sufficiently large values of k was announced in 2021 by Dong Yeap Kang, Tom Kelly, Daniela Kühn, Abhishek Methuku, and Deryk Osthus."
Accordingly, I will remove the entry from this list. ^-^ Atomic putty? Rien! (talk) (talk) 13:23, 7 July 2022 (UTC)
