Notability

@AnomieBOT @David Eppstein Hello, I saw your notes about this article, and I need to highlight that (the University of Jordan) which is the biggest University in Jordan, officially announced that this professor and his team solved a major open mathematical problem that had remained unsolved since 1948. and you can search and check this, Thanks.

I can certainly check that he published a claim to solve this problem in a dubious journal that has been de-listed from both MathSciNet and zbMATH. I don't need a press release from his employer to discover that. But, as they say, extraordinary claims require extraordinary evidence. —David Eppstein (talk) 20:37, 24 November 2024 (UTC)[reply]

Hello @David Eppstein, can I have more information about this dubious journal? RH (talk 14:01, 25 November 2024 (UTC)[reply]

The journal is European Journal of Pure and Applied Mathematics. You can search for it on zbMATH and MathSciNet. MathSciNet will tell you that it was indexed from volume 1 to volume 15 (2022), and is no longer indexed. zbMATH will tell you roughly the same thing except that it was indexed only up to volume 12 (2019). These are the two main databases of all mathematical publications and de-indexing is a serious step taken only when their editors believe that the journal is no longer trustworthy as a source for mathematics. —David Eppstein (talk) 17:04, 25 November 2024 (UTC)[reply]
